Its a fun game, I like the puzzle aspect of it. Im stuck at the level where I have five bats, but nothing else. They don't deal damage, and there are no traps to knock the player into, so I couldn't figure it out. :)
Yeah I was stuck at the same spot. Cool game though. Also on the topic of tutorials, maybe you could try to make the UI clearer, maybe by making it flash or something. Either way, cool game!
