If
this is the game, I don't think it's just your own ineptitude.
A quote from the linked review:
Imagine a McDonalds PlayPlace designed by B.F. Skinner. Each room contains several levels of multicolored cubes, all of which can be picked up, thrown around, or busted through a la Minecraft. Your goal is to toss a certain kind of cube into an uprising stream at the center of the room, 30 times. Easy enough, in theory. But you are pursued relentlessly by a demonic jack-o-lantern that blows up several cubes at a time or traps you in a concrete cube-box, and it’s all too easy to fall through a hole in the cube-platform and into the water below, which sets you back 3 points every time. The controls and physics are sluggish and imprecise; you never know how far a jump will take you or whether a tossed cube will make it home. It feels like playing basketball inside Jello.
