You can rotate the blocks with Q and E, but I understand that due to the pixelation and the visual effects, it ain't very clear.
I really enjoyed the visuals, theme, and the atmosphere of this game. However, this game wasn't made for me. I don't particularly enjoy Tetris hence,do not know what to buy. It's overwhelming for me.
However, the visuals and feel of the game was enough to get me playing, which is good. Others can do a better job critiquing the gameplay but this is definitely a good looking game.
