Very amusing premise, and the execution is just as funny. Great clean interface. The small number of inputs makes the game easy to pick up and the physics-based gameplay adds complexity and challenge.
The glue wasn't as useful as I would expect - I tried using it to avoid damage when the box was bouncing around.
I'm sure glue could be used strategically to keep the box on a certain side, though that was a bit too hard for me to do.
Minor bug: somehow, the box escaped and I won!
