This concept makes for a great puzzle game. As someone else mentioned, I think the controls are a tad clunky. I found myself wanting to use f to throw the dice as well as pick it up, and trying to use the arrow keys to increase the value of the dice platform, though that might not be the best control scheme either. Still, it was really fun and I had a couple of great "aha!" moments, which is exactly what you want from a game like this!
