As other people have said, a hold function and being able to hold the left/right arrows to quickly move left/right would be awesome.
Besides those two nitpicks, this is a very, very unique take on Tetris, and it's really unfortunate that the Tetris Company is as sue-happy as they are, because I'd love to see this turned into a multiplayer online game. Incredibly fun and challenging, this is seriously an awesome idea.
Difficult but challenging. Great idea. Less is more ;)
At first I think to myself "pffft, no biggie, I'll just look at one of the screens that's not the falling color". But after one mistake, this game becomes extremely challenging. The universally simple game of tetris becomes a very interesting and difficult puzzle here. This is perfectly executed. Great job guys!
This is incredible.
