Great game, there is no bug on 7, you just have to move them a bit differently. It's all logic and common sense.
Awsome game, really keeps me thinking
I would give a 10 just for making it 3D game
I freaking love this game, holy crap my mind is tingling from all the possibilities as I move each block so carefully. AMAZING!
I'm going to die of old age before I finish T^T
