After tinkering with it for several minutes, I'm still unsure how this game works. Lifts work but only sometimes? Not all dice are lifts? Sometimes when rolling depth-wise I fall off the map?
I have a suspicion that it's a 3D world with a orthographic camera and that moving in the depth direction totally messes up your collision detection, but I can't be sure. Hard to offer more since I could only complete one level.
