Fun game! Is there an ending to it, or does it continue indefinitely?

Can you provide an Android APK directly to itch that doesn’t require Google Play Services? I specifically buy games from to avoid that.

Hey. I played your game on PC and I have to say I liked everything about it!

The graphics are cool, the controls fell good and fair. The difficulty curve is very balanced.

Keep it up!

Super solid game! I love games I can jump right into and quickly play to get my fix! Once I get my phone working again I''m gonna love this on my commutes :) 

Great Work!


Very nice game!! 5 STARS!!!!!!

Although I think it would need a configuration for the controls (on PC) and that you can change the language.

Very good! Nice Work!!!

Thanks so much, we're glad you enjoy Astral Defense!

The PC/Mac version does come with a user defined keybindings option in the menu, although no  controller support has been implemented. Localization would be a pretty large undertaking because of the way Astral Defense's art/animation was tediously created.
