The next Celtreos patch is live!

Enhanced Soundtrack

A number of songs have been improved!  Also, the end-of-game story sequence has an entirely new song and a revised version of the credits music.

Artwork and Animation Improvements

As usual, a number of small tweaks throughout the game.  Several bosses have more detailed artwork, among other changes.

“Big Sur” and Apple Silicon

The game has been tested on the new macOS “Big Sur” release and is supported.  It has also been built with direct support for both original Intel Macs (x86_64) and new Apple Silicon Macs (arm64).

New Negative Item “Reduced Range”

Be careful…there is yet another power-down in the game, “reduced range”!  This will significantly limit the distance that your weapons can reach, for several seconds.

New Enemies

There are even more types of foes in the game!  You can see them in stages such as “Hyperspace Pursuit” and “Colony Evacuation”.

Artwork and Animation Improvements

Lots of small new details all over the place!  Several enemy projectiles or firing effects have been improved.  Even your player ship’s tail exhaust looks cooler now.  The background in “Hyperspace Pursuit” is now a lot more intense, and some other game graphics have been tweaked as well.

Extra Boss in “Shipyard Attack”!

At the end of the game there are now two boss fights, back-to-back!  The new boss has a wide variety of attacks and moves, some of which are not used by any other enemy.  Oh, and your ship’s sensors cannot detect how many hit points it has.  Prepare yourself!

More Base-Speed Options

You can now choose “X-Low”, “Low” or “Normal” base ship speeds in the main Options Screen.  These are particularly useful when playing with certain game controllers or other input devices that may lack precision.  The base speed is only the default; as before, your ship can still go even slower using the Slow mode in-game (e.g. Shift/Caps-Lock key or A/X buttons), and your ship still automatically moves a bit slower in dense-layout stages such as “Space Station” and “Refinery Raid”.

Game Tweaks

Minor gameplay improvements in various stages.  Small enhancements to some effects.  Also, a handful of optimizations to ensure a good frame rate in high-traffic cases (like lots of bullets on screen).

Updated to 1.54

A big update to Celtreos!

Huge Artwork Upgrade

Several parts of the game have had their artwork significantly updated. Backgrounds in most stages are now much more detailed, and there are even some cool new background effects (like swirling lava pools in “Sharp Descent”!). Some bosses are more detailed. There are even some tweaks to the UI.

Weapon Array Swapping

Weapons are even more useful now because you no longer have to stick with your choice of array for the entire game! At the very end of every boss fight, up to three alternate weapon arrays will now spawn. You can choose to ignore these special power-ups, or touch one of them to use a different array of weapons! Note that this not only swaps out the set of power-ups that can be found in future stages but it changes the slots for any weapons you currently have. For instance, if you had “Seeker” (a locator-class weapon) and you choose to switch to an array that has a different locator-class weapon such as “Phaser”, you will no longer have “Seeker” but you will have “Phaser” instead.

Mac App Icon Update

The Mac app icon has been updated to match the rounded-corner style of icons on macOS “Big Sur”.

Lots of detail has been added throughout the game, along with some cool new effects!
