I tried your game out and well here some things I like to ask. What is the objective in the game, I mean i see those creature was i suppose to capture them or do i just beat all the enemies that happen for them. That is what was confusing me.  Just it help to have a bit more idea to the objective or what to search for exactly. I know it was the creatures but was it to beat them or something else. Just wanted to mention that. Still nice design you set up and ran well.
