Really cool game! Honestly, I really really enjoyed it- from the art, to the music and the general idea, there is nothing that you could have done better! I really liked that you explained the functionality of the animals while hovering above them, it was much more intuitive and integrated in the game than to explain it at the beginning.
Different roles having different functionalities that you have to pick is really entertaining and while the idea is simpel, it is difficult enough to be catchy and not become boring.
Really good job, I enjoyed your game!
