"What I think about it" is I think someone played Little Nemo the Dream Master. I don't think we have a Little Nemo clone on Newgrounds yet, so this is a nice addition.
Much better than your previous game (which wasn't very good). Make more like this, and not like that.
Only thing is, and I managed to get through the game without losing any animals, but had you lost an animal, you would have been stuck in many spots. It's generally not a good idea to design in such a way where the player can get stuck even though yes many retro games did exactly this.
