This is such a good (and unexpected!) game! I had more fun playing this than I should have! Definitely one of my favourites so far.
If I could suggest something, that would be refining the controls? I know the feeling is supposed to represent a fish's struggle on land... But I could feel the struggle too xD
What I liked the most were the humans! They co-operated so efficiently it looked like they were controlled by a human! xD
