Great game, but I couldn't finish it because one of the later levels (one with Preta, Bird, and Snake), I couldn't get Snake to appear, no matter how many times I restarted.
I was wondering if you might consider making a level maker for this game? There might be a way to encode / decode level files so that people can download and import them from each other by sharing w/o the need to store them on a server. Just an idea.
