Hey you really made something original there. Very nice entry. The best step was clearly the 2nd: the root is the coolest and most original phase of gameplay (to me). A few notes in case you intend to improve this version and bring the game a bit further : First step has a solid gamplay but isn't very clear, it looks more like atoms than mineral world. Third step is nice, but the duck moves are very rigid and a few animations would help. Finally the last could be fine but I really felt like there were some collisions detection problem, i missed almost all my fires. Again, impressive concept and implementation.
I did feel a little remorse having to shoot at the ducks after being one myself, but such is the way of life.
Great job!
