Very cool.. though it is annoying that it seems like you aren't really going anywhere while playing. That's one of the most important things about games: the player needs to feel some sort of progress. Of course your organism grows and the other beings around you get harder to deal with, but that's about it! Nothing substantial changes.. as far as I could tell, at least. Also, given the fact that there is no way to save a game or even pause it, I assume the game is built in such a way where players are expected to just sort of come back when they feel like it, starting the game over every time.
