Chain Reaction by Tororoxu is a short space puzzle shooter game made for PICO-8.
In this game, you need to avoid enemy waves in a damaged ship that can only fire its weapon once. This game is a small prototype for this idea with only two levels. Use ‘arrow’ keys for movement and ‘x’ to fire. Once your level is cleared, it will show you stats of your high score and damage. You can press ‘x’ to move on to the next level.
