Loved it! I definitely was not expecting the change that happened, so that's really cool. The theme is there and I enjoyed playing. Didn't see any (unintentional) bugs.
I feel like it might have been cool to have a lose state on the second part, and playing on a big monitor is a little disorienting since you move so fast across the screen, but I think the disorientation is part of the chaos and makes it fun.
Production quality (menus, credits, etc) is awesome - I need to practice that stuff so it's really nice to see it looking very good and working perfectly.
