Shoot the enemies with primary colours to destroy them! Arrow keys to move, Z to shoot, space to change colour. Purple, orange and green are composed of multiple colours, so they will need to be shot multiple times. The alien-looking white star is a powerup, it kills all enemies on screen. You lose if ten or more enemies are on screen. The left is your score, the right is the global highscore.
Lmk in comments if you get a global highscore! :3 Also, this was made for a small project, was not intended to be a full game. It's more of a concept, so feel free to remix and expand on it.
