Glad you like the artwork! I actually had some animations for it but didn't get to hook up all the animators. And nah, you're not stupid at all - the lack of animations means I also didn't have the victory/success animations working when you find the cake. The plan was to have a little victory animation and then load the next level, but I had some people visiting from out of town and had to stop working on it earlier than I would have liked.
Thanks for checking it out though! I'll have to look into that physics exploit you mentioned...
