Beat it! Took me until the last level to realise the rock-paper-scissors thing, I was just trying every colour up until then randomly. Should've read the description more carefully!
You can fire as many times as you want, so even though there is a higher score for shooting only once it doesn't feel like it's integral to the design of the game. Without the high score for one shot, the game is pretty much the same.
Also, since the bullet despawns on hitting an enemy, there's no way to complete levels with 2+ enemies in a single move. Or am I missing something?
Pretty original idea, great job with this!
