Checked it out and played about 5-10 minutes of it so far. One thing that I got stuck with is your region triggers.
When I played at first I thought it was only a one screen game with nothing to do because I couldn't see that I had to go down through that little ravine just because of the camera angle.
If I hadn't opened it in the editor I may not have figured it out.
And one more little cosmetic thing: A main menu camera is really easy to make, it's as easy as inserting a spec cam and naming it camera_Main iirc.
After I figured out where to go though it was cool and even funny to see a chicken dodging fireballs and stuff. Good job.
