not all that bad
some minnor problems
1.sometimes die RANDOMLY
2.Wall jump would be 100 X better if it was replaced with the jump button
3.Music was AWESOME, just OVER used.
4.kinda repetative.
5.nothing really fancy, could have been alot better by adding the feature of the REAL tetris rules (4 connect, that go!)
6.background makes no sence :S
But other then that, really nice job man
