First, I love the look of the game. I watched your making of video and I'm so impressed with your graphic talent (I have none of it).
Second, I thought the difficulty was perfect. It too me three tries, but I finally beat the level. It all felt very polished and bug free.
Third, great use of projectiles and animals. Well, thought out.
If I had any complaints it would be about the story. It felt sort of tacked on at the beginning and then the actual game didn't seem to advance it at all. I think if you could integrate more of a story with more level going forward it would be fantastic.
Still, I really liked this game a lot. Very well done.
