A very cool take on the classic game, i found it a bit too easy to balance and the speed/difficulty didn't ramp quite fast enough but it was fun overall. Congrats and good luck!

It is interesting that a lot of people did not think it ramped fast enough, I grabbed the formula for speed ramping from the tetris wiki and actually decreased the number of lines cleared necessary to increase the level. Maybe it is because each side ramped separately, so to get both boards from 1 to 2 requires clearing 16 lines rather then the 10 that increasing the whole board would take in regular tetris.
