Not too bad, add a bit of music and sound effects and this would be a pretty decent yet simple game.

Very interesting concept, never seen something like this. I mean the "punish the player for his mistake and make the game harder" part.

A decent time waster.needs some relaxing music.

Perhaps slower rotation speed but that may be just me.

This game is really chalenging, it's not hard, but the gamer requires really big concentration.
this game is amazing. What really cool by this game is, it's better with the rotating, not just like normal stack, where only the block moves.
