The style is so cute, and the critter designs make me want to cherish and protect them (I would die for my zipduc). You did an awesome job and the game is really fun to play.
The only thing I can think of that might make the game even better would be some way to see every critter's health (both your team and the enemy's) during battle? Though it is kinda fun and chaotic to not know exactly what's going on. Amazing game!!
