Nice game! Looks good and organic. A bit easier than Tetris and i like that
Maybe a bit too easy tho. And i found a bug: you can rotate a piece infinitely just when it touches the pile. So it was even easier for me
I like that if you have gaps you can still complete lines above to get to the gaps. But do i remember correctly that it takes away the score? If i do then maybe it shouldn't, loosing a line to nothing is a big enough punishment
