Is my bad, the game mechanics aren't well explained , that game is a mix of rubik, tetris and 4 in a row... well that what's intended, if you put 7 blocks in a row, you're gonna be rewarded with 2 rotations and then you're gonna have the chance of moving each row like a rubik's cube...
so I've to polish the user experience , explaining better how to play , also I've to add block's animations (destroy, move,rotate,etc..) and a new game mode.
Thanks for your feedback ;)
