Well hello there! its me! Edmund!

Ive noticed some of you are VERY MAD about some recent changes to the game, and some of you are not so mad, hell some of you are even please! . so i wanted to pop in and clear up a few things.

From this point forward, when we update the game with content / balances, we will make sure there is a long list as usual.. AND a short bullet point list of all the biggest changes so you can see how the buffs outweigh the nerfs, in hindsight i think if we had done that last update you may have noticed more of the improvements and let a few of the nerfs slide.

that said, we do hear you.. and as an olive branch id like to offer a small little update, an update that you have control over!

Tell us your top 10 most useless/horrible trinkets.. and we will buff them!

Also please let us know your top 3-5 evil deals you NEVER TAKE as well!

Post these in the comments here, or make a video/reddit thread and link them to me on twitter.

I hope you all understand that these updates, though at times feel jarring, are a fun way to experiment with power level, balance and add challenge and excitement back to a game that many of you are still playing daily. not all changes are set in stone, but changes can keep things exciting and fresh!

The team is eager to please and always listening!
Stay tuned for more!

-------------------------

while i'm here id like to signal boost this recent mewgenics preview video.

Many of you responded to the trailer with "SHOW US GAMEPLAY!" and "BUT HOW DOES IT PLAY!?"
well this 10 min video should give you all you need!

[previewyoutube][/previewyoutube]

We should be announcing a release date in the coming months via a fun lil trailer and then maybe start streaming at the end of summer to build the hype and answer questions.

Good morning/afternoon or evening. It is I, Tyrone. A little light reading while you're sitting on the toilet this afternoon. Alex was on there for a while today. Too much spicy Mexican, I guess.

You'd think that going from v1.9.7.10 to v1.9.7.11 would be a very small incremental change. Like, "Hey, we fixed being able to drop bombs while typing in online chat, you're welcome!" But noooo, the Isaac team has been working tirelessly to bring you the following improvements:

Features/Balance Changes:
Adjusted the behavior of Cod Worms staying hidden for long periods of time
Adjusted the behavior of Kineti to only use their rock-grabbing action if they are on screen with the player
Adjusted Blood Cultists to not fire their blood attack from off screen
Lowered the tear height of red champion Mega Fatty’s puke attack so that it doesn’t always fly over Isaac’s head
Siren will no longer charm Isaac’s Heart or Lilith’s Incubus
The Amnesia horse pill will now unidentify all previously identified pills
Tainted Maggy’s bleeding hearts now provide half the charge of a regular heart container when used with Sharp Plug
Tainted ??? will now swap poops and keys when using a Bombs Are Key pill
Added a 1% chance for Wheel of Fortune to spawn a Crane Game
Gave Punching Bag back his ability to block shots
Removed Glowing Hourglass and Book of Shadows from the Tainted Lost pool
Using Meat Cleaver on an angel will now award only one key piece
Delirious has returned to a fixed 12-charge item. Bosses have had their health and damage overhauled. They will take 1 damage per hit and 5 damage from explosions. Spikes, fires and red poops do no damage to them. Their health will deteriorate steadily and their color will slowly turn more gray until they reach 1 health
Delirium Mom’s Foot is no longer sped up when Delirium gets enraged. A minimum delay of one second has been added between transforming into the foot and the stomp attack. While in Mom’s Foot form, Delirium cannot fire additional projectiles. These same behaviors also apply to Satan’s Foot
Replaced Mars’ shield bubble with i-frames which will still allow free entrance into Curse Rooms but will not allow free plays to Devil Beggars and Blood Donation Machines. Impact from a Mars dash no longer creates fissures that destroy rocks. It instead creates a ring of fire that applies the burn status effect
Jar of Wisps has returned to a 12-charge item. Its first use will grant two wisps and every wisp spawned has a high chance to be of a special variety.
Pausing the game with Gitched Crown will not pause the item rotation, and will instead give the rotation a burst of speed
Adjusted the proc chances of several Abyss locusts that were too powerful
Knockback from farting locusts has been increased
Adjusted the stat boost from Star of Bethlehem to match Hallowed Ground
Wisps spawned from The Bean and Kidney Bean will now expire when changing rooms
Completing a Secret Room with a Greed fight will now allow access to adjacent Challenge Rooms
Added enemy spawn indicators for Boss Rush, Challenge Rooms, Great Gideon and Greed Mode
Golden keys and bombs can now be spent at the Key Master and Bomb Bum to guarantee an item drop
Item charging with Battery Bum while holding multiple active items now prioritizes filling up each item before overcharging
Pause (the active item) now synergizes with Black Powder allowing circles to be drawn while a room is paused
Added a very low chance for most bosses to drop a thematic item on death
Increased the range of Dr. Fetus with Number One and Pluto
Ludovico Technique now grants a .2 shot speed increase
If the Mega Satan door has been been opened, using Forget Me Now and restarting the floor will keep door opened
Increased the rarity of D20 in the Greed Shop
Added an option in options.ini to disable the Ascent voiceover
Fully rerolling a character with D4, D100, Dice Room, Missing No., etc. will no longer reroll the starting passive items of a character if they have unlocked them. Using a Stars? card will also not consume starting passives. Starting active items can be rerolled. The items that will not be rerolled are:
Cain: Lucky Foot
Eve: Whore of Babylon and Dead Bird
Samson: Bloody Lust
Lazarus: Anemic
The Lost: Holy Mantle
Lilith: Incubus and Cambion Conception
Bethany: Book of Virtues
Using Clicker to change characters now provides that character’s intrinsic passive items. These items are lost when changing characters again. Reduced the chance of Clicker removing the most recently acquired item to 50%
Added various new sound effects
Daily Runs:
Using Meat Cleaver during daily runs will cause each resulting split monster to give half of its normal score
Frozen enemies will count as being killed and will award score in daily runs
Killing Uriel and Gabriel during a daily run will now only award score the first time each is killed
Stage bonus in daily runs has been modified to accommodate different end goals
Stage bonus is fixed for each stage. XL stages now award the stage bonus for both floors. Using a Forget Me Now or a 5-pip Dice Room will not award additional stage bonus
Using a Forget Me Now during a daily run will now award half the exploration bonus during the repeated floor. Any additional replayed floors will not grant any exploration bonus
Fixed an issue where using Forget Me Now on the final floor of a daily run would result in an incorrect time on the score summary
Fixed an issue where quitting a practice daily would reset the daily win streak
Exploration bonus from red rooms opened with Red Key, Crystal Key, Soul of Cain and the Moon? is capped at 2,000 points, after which they award no exploration bonus
Added Alt Path, Home and Delirium to the daily rotation. The new schedule is:
Monday: Mother
Tuesday: Tainted Characters
Wednesday: Delirium
Thursday: Home
Friday: Hard Mode
Saturday: Grab Bag (random character, end goal, difficulty)
Sunday: Mega Satan

Bug Fixes:
Fixed an issue where Glowing Hourglass was not expending charges correctly in some scenarios
Fixed an issue where Gigante Bean would apply to enemy farts
Fixed an issue with Jacob and Esau classic controls that would cause cards and active items to be used together
Fixed an issue where dashing items were not properly stopping when attacking Mega Satan head-on
Fixed an issue where R Key could be used while picking up an active item, allowing both the active to be acquired and the R Key to be used
Fixed an issue where Wall Creep and Blind Creep would infinitely devolve into each other
Fixed an issue where using Genesis after a completed Ultra Greed fight would completely reset the floor
Fixed several issues which allowed Lemegaton wisps to exceed their cap
Fixed an issue where Lemegeton item effects were retained after using Genesis
Fixed an issue where mapping items granted by Lemegeton would not activate until entering the next floor
Fixed an issue where shrunken champion enemies could still damage Isaac when killed
Fixed an issue where Tainted Eve would not refund the appropriate amount of health if Rotten Hearts were turned into clots
Fixed an issue where leaving the room while a crane game was paying out could result in the item dropping but the machine not advancing
Fixed an issue where Tainted characters would not receive charges to their eternal item from Battery Bum unless they were holding another active item
Fixed an issue where taking too many of a single pill type could prevent the run from being exited and continued
Fixed an issue where Vanishing Twin could spawn an item pedestal on the same tile as the trapdoor
Fixed an issue where Dead Bird could persist between rooms if the player had only soul hearts
Fixed an issue where Monstro’s Lung would fire arching shots from Ipecac and Haemolacrya directly at Isaac’s feet
Fixed a softlock that could occur when using Eraser on Dogma
Fixed an exploit with The Bloat’s hitbox that allowed players to safely stand on top of him while repeating the same attack
Fixed a softlock that would occur when using Dataminer to reroll Dad’s Note
Fixed an issue where Echo Chamber’s stored effects were lost when exiting and resuming a run
Fixed an audible skip when looping the Mother fight, Isaac fight and Devil Deal music
Fixed an issue where jumping into the Mother fight played a teleport sound effect
Fixed a desync with Plum Flute and Book of Virtues
Fixed an issue where status effects were double applied in some cases when entering a new room
Fixed an issue where players could get golden trinkets from champion monsters before they were unlocked
Fixed an issue where bombs could be dropped when typing in online chat
Fixed an issue where Lil’ Portal could spawn directly in front of doorways
Fixed some issues with Found Soul and Clot familiar positioning when teleporting between rooms
Fixed an issue where Found Soul was able to get and lose Abyss locusts
Fixed an issue where Epiphora was not resetting when changing firing direction
Fixed another instance where the D4 could change the pool ID of items, allowing them to be rerolled into a specific pool
Fixed an issue where Mama Mega and Flat File effects could persist into deathmatch
Fixed a crash when using Clicker, gulped trinkets and Jacob/Esau
Fixed an issue where Milk! was higher priority in the familiar order than Incubus
Fixed incorrect challenge names displaying when creating an online game
Selected challenge name now appears in lobby list details

Adjusted Mega Satan’s phase 2 fire attacks making their visual line up more closely to their hitbox
Fixed frozen enemies not properly triggering the on-kill effects of Charm of the Vampire, Lusty Blood, Toxic Shock, Jar of Flies, Samson’s Lock, Eve’s Bird Foot, Bat Wing, Sigil of Baphomet, Vasculitis, Death’s List, Berserk!, Red Stew, 4.5 Volt and Jumper Cables

Thanks to everyone who pointed out issues and made suggestions! xoxo

It’s me, Tyrone, here to tell you about some stuff. The good stuff

We've been hard at work on the next patch for Repentance+, and there’s a lot coming your way. There are loads of bug fixes, optimizations to online modes, balance tweaking and feature improvements that we hope veteran and beginner players will both appreciate.

Here’s one cool addition that you can look forward to. You know how the Key Master and Bomb Beggar often get overlooked, because you don’t want to use up too many of your resources to keep gambling for their big payouts? Well, pretty soon you’ll be able to pay them with a golden bomb or key to receive their item payout instantly – at the cost of that golden status, of course. There are some more changes in store that I can’t tell you about just yet, but please look forward to the next update.

Some of you may have seen us messing around with AI-controlled Isaac over on my Twitch stream. We’ve enabled chat commands, where viewers can make Isaac move to specific spots, attack, bomb and use his active item, all through Twitch chat.

It’s been fun watching the community try to complete runs together. We’re working on more ways for chat to interact and team up. If you have specific commands you’d like to suggest, please let us know. More to come on that, too!

Now here is Edmund to talk a little bit about a project that’s near and dear to his heart: his next game, Mewgenics.

--------------------------------------------

Edmund here. Sorry for hijacking the Isaac blog. I promise to only do it one more time.

So, for those of you who don’t know, I’ve been working for a very long time on an endless cat-breeding RPG called Mewgenics. If you love Isaac, you’re going to feel right at home in this one.

Mewgenics is built with the replayability, randomization and strategic depth that made Isaac so addictive. It has branching paths, tons of items, spells and mutations to discover. The game genre is completely different, but it’s designed to keep you coming back again and again, just like Isaac.


Mewgenics actually takes place in the same town where Isaac and his mother lived. So if you’ve spent any time getting lost in the lore of Isaac, there are definitely some cool connections to watch for. And the soundtrack by Ridiculon is the best they’ve ever done.

If you’re someone who loves the challenge of Isaac’s endless replayability, and enjoys unlocking new items and exploring new combinations, I really think Mewgenics is going to scratch that same itch.

There’s an absurd amount of depth, and you can easily sink hundreds of hours into the game without seeing everything we crammed in there. It’s got the same charm, the same humor and the layers of complexity you’ve come to expect from my stuff. It really feels like the culmination of my experience making games.

If you haven't seen the Mewgenics trailer I just released, please check it out and share it with your friends and family. I think you’ll be pleasantly surprised by how familiar it feels, even though it’s something new. Go add it to your Steam wishlist and get ready because it's finally coming!
Alright, that’s enough from me for now. Stay tuned for the next Repentance+ patch, and keep an eye out for more updates on Mewgenics!

And here's the link ONE MORE TIME!

Sorry for the delay in posting this update(got a little sick, I blame Alex). It was more important to get you the patch than to hold it up with patch notes.

Bug Fixes
Fixed an issue where Berkano locusts could persist when used with Glowing Hourglass
Fixed an issue causing The Stairway, Card Reading, and Isaac’s Tomb to not function properly
Fixed an issue where the Karma trinket could show up in daily runs and challenges if the trinket pool was depleted
Fixed an issue where force quitting a daily run would not reset the win streak counter
Fixed an issue where the restock machine would still double reroll if destroyed via coins instead of bombs

For Modders
Game():RerollEnemy(Entity) no longer crashes
Added Lua enums for Deathmatch and Lil Portal backdrops, NUM_BACKDROPS now works as intended
Level:AddCurse() will now apply the modded curse instead of always applying Curse of the Unknown
EntityPlayer:QueueItem() no longer crashes
ItemPool:RemoveTrinket now properly removes modded trinkets
Setting the challenge mid-run can now properly set to the ID of a modded challenge
log.txt no longer logs an error if all attributes are not provided
Updated the Lua ButtonAction enum to match what's in code
Fixed an issue where wrong kerning value could get applied to a character set
