This is very clever. I love how the difficulty naturally scales by the nature of having more weapons makes you a bigger target. I'm not very good at the game, and I always lose shortly after the bomb enemies get introduced. I am colorblind, and I have some trouble determining if a bomb is friendly or not. Also, the bombs seem to just slowly accumulate without an easy way of clearing them (other than sacrificing what you've collected). I liked the game; I just wish I wasn't so bad at it. :P
