Creature design - Amazing; Overall art - Amazing; Gameplay - Very Enjoyable.
Ah very nice submission! Not too cozy imho, but very cool.
As far as suggestions go, I think three clicks to attack and the space bar to return to the map are unnecessary. Have the creature attack as soon as you click on the enemie(s) you want to attack and return to map after boon selection. But that's nitpicky stuff.
The evolutions are really cool. The bunny one made me actually go: woah :D
