The idea is alright, but this is one of the more frustrating platformers I have played. You have to get the cube pixel perfect in order to make a jump, sometimes, the cube skids when it lands, the levels seem to time out on you, and I have been killed by the smoke despite it not even touching the cube. It is way too frustrating! As for what I like, I like how the levels destruct when you hit that teleporter. At first, it seems you are trapped in an endless cycle, but then, what's that?... That's pretty cool.
