Important safety check before landing:

[h3]!!! Savegames from version 1.0.0 are not backwards compatible. That means, as always, you can go to the Steam Properties page and select the previous version 0.9.6 to continue enjoying the last paradise.[/h3]
[h3]Older maps from the Steam Workshop are no longer compatible with version 1.0.0 and have already been declared incompatible. Anyone can update the maps using the map editor if desired.[/h3]

There was a chance to win a key by streaming on lurkit.gg (from a certain size) and to test the pre-full version from today. Journalists were also contacted and given a test account.
But, ladies and gentlemen, don't forget that Summer Islands is just too small for streamers and journalists.
In the last few days, testing will be carried out and small bugs will be eliminated.

Next on the program
Make sure your management talent is well secured. You'll need it to turn island paradises into hard cash! 💰
Get ready for unexpected surprises like sudden tropical storms. Don't worry, it's all part of the adventure! ⚓⛈️

Thank you for choosing us. We wish you a pleasant journey and many profitable beach moments! 🌊✨

Blog post: 2024 summary and outlook for 2025

Hello everyone,


We wish you a relaxing Christmas again this year. We hope you, your family and your friends are all well.



Thank you very much this year for your support and also the nice and interesting conversations at all the game festivals we visited this year.
It was really fun and a real win for Summer Islands and us!!!

It's not long now until the full release of Summer Islands on 25.01.2025

The last few weeks have been a bit hectic, alternating between the relaxed feeling of “Easy Going” and “WE WILL NEVER DO THIS!!!! AAAHHHH”
We were able to implement a lot. All the construction sites and TODOs are currently on the home straight. The biggest construction sites have been completed and the campaign is ready for fine-tuning.

The biggest “nice-to-have” tasks are still the languages and making the whole thing compatible with the Steam deck again after all the changes from the last few weeks.
I don't want to make any promises about the Mac version for the full release yet. It might be coming soon. But “actually” it should be doable :D

Some new buildings have been created that still need to be added. To tease a bit, we're talking about basketball, jeep rental, yoga parks, shopping malls etc.
The “research tree" is rounded off with the new buildings.

As you can already see above, a small parrot has been integrated as a help, which draws your attention to the help menu and the 2-minute video tutorial.
We have literally rounded off the minimap and added helpful buttons.
You can also use the helpful buttons with shortcuts. This also includes the colors around the buildings or the FlateMode.
We have decided to always leave the colored outlines at capacity. In flat mode, you can switch between player color and capacity utilization.

Our full focus is currently on the full release.
But we already have several other projects in the works. The next project is a turn-based strategy game called Streak Of Power.
The Steam page will be online in a few days.
Afterwards/simultaneously there will be a Summer Islands boardgame and we won't run out of ideas ;D

or our newsletter on our website:

Last but not least, I would like to say a BIG THANK YOU to you and your support for Summer Islands.
You are the heroes and a happy new year 2025 to each of you.

P.S. If you ❤️ Summer Islands, we would be very 🤩 about a 👍 Review.

October 2.Update 2024 [v0.9.6] with announcement & bug fixes

Hello everyone,


Well... you're probably wondering “The next update was supposed to be the full release, right?”
Yes, it will be ... Moved ;)

Yes, we wanted to feel like the big development studios and delay our release for a while.
But for us it's only 1 month.
[h2]Planning for the full release is now 25.01.2025[/h2]

The reasons for the shift are as follows:

1. there were more bugs for the last release than expected (I would like to apologize to everyone for the bugs and thank you for your help).
2. the day job requires more “overtime” in the next few weeks and another exhibition in mid-November and the XMas madness comes right after that.
3. the strongest reason is: The release number of further games in December is enormous. Let me explain that a bit.

Whoever publishes their game on Steam usually has a goal to make their game better known. This doesn't always have to be the case, but there is a high probability that this applies to most games. The goal is to be recognized by the Steam algorithm and to get on the Steam front page. You don't even have to be visible on a large banner. No, just the several columns below “New & Hot”, “Coming Soon & Popular” or something like that are enough. The goal is to get there!

That's why we talked to several friends at Polaris and checked out the situation. Our result is a shift from the end of December to the end of January. For us, this means not only the chance of more attention on Steam, but also several weeks more time.
For you, this is a delay of 5 weeks. I know, I know...most of you have already taken vacation for those days and planned big release parties. I hope some things can still be canceled or moved, otherwise it went a bit badly. I'm really sorry about that.

In summary, the original release plan lasted exactly 1 week and so I used the last few days to fix the most serious bugs here with this version.
For this version there is therefore “only” this announcement about the shift to 25.01.2025 and some bug fixes.

Thank you for your support, feedback and patience.

P.S. If you ❤️ Summer Islands, we would be very 🤩 about a 👍 Review.

Have fun
