I don't like the idea of the score going in the negative, it could be a fun concept in another game, but I don't think it fits well with the theme of this game. The concept of changing the colours is nice though. I did have some issue with right clicking just outside the play area when I was playing on WebGL non-full screen mode. Good music. Gradual increase in difficulty (felt balanced). The game says level complete and suddenly ends, instead it could have said Game Over. The dodging part of the game is really fun, changing colours to dodge bullets while collecting those coins was really fun, would have loved if the level was a little extended. Felt the game ended really quickly.
