That song is BOPPIN. I love it. Nice.
It would have been nice to get some sort of feedback if a powerup was good or bad. But even my bad-at-tetris self cleared 12 rows before it got too fast. Well done!
What's not to like about a well-done implementation of Tetris, especially with an extra twist or two?
I like the addition of the tiny sized pieces!
As for the powerups, it's indeed somewhat hard to catch what effect they had. At least until I hit the first one that bumped all rows up by one...
