Playability:
You've made a compelling rage game here and I actually had a lot of fun with it. Obstacles are rather brutal which is great for this genre.
Theme:
The theme doesn't feel strong on this one. It's kind of present in that onlookers throw objects but it's not really heavily tied to gameplay outside of that.
Cleverness:
Leaning back and forth to keep balanced is a great mechanic and not something I've seen before. Reminds me a bit of QWOP but on a tight-rope. Nice work!
Artistic Style:
Soft colors and consistent art throughout. You did great on this!
