Very very interesting, love the idea
Only problem is its not very sustaining, what i mean is it doesn't have any 'i want to keep playing this' power. I only played it for about 3 minutes, and then got bored, but i did enjoy the 3 minutes for what they were. The music and the feel reminded me a little bit of an old game called Creatures, that had a smiliar touch.
Anyway ive rambled on, thanks for the game, its cheered me up.
