Cool game idea, I really like the balancing mechanic. Good job :)

Interesting take on a game concept that's  rather popular. Running games are pretty common these days, but I've yet to see someone make something which involves you balancing a platform as you go down a runner. I'm not sure why, but I couldn't drop any boxes (Perhaps I just didn't get far enough).

My character was sliding around quite and that was rather frustrating as well. I think if that hadn't been the case it would have been more satisfying to play.

Cool mechanic, I like it! Having the player slide along the platform as it moves (rather than having the player move along with it) adds a nice little challenge!
