uh.. it's been done..

why would you try to replicate a game that was beat to death 20 years ago? constructive criticism would consist of 'make something original'...

fucking love me some Tetris

Tetris is such an amazing game, I sat and played for 45 minutes before I realized what time it was. I can kill me some tetris, thanks for helping me waist my boring afternoon.

It's OK

Its pretty ok. I like the increased difficulties are kinda fast. Maybee u could add a difficulty menu. It*s a little irritating that when you push a button to make the tetriminos go 1 space it sometimes jumps 2. But otherwise pretty great and a good flow. :D

it gets too hard too quick

other than that it was boring and the controls did not 'flow' well for me. make the space bar the key that spins the pieces. good job tho on converting tetris to flash!

" Its just tetris "

For a "just tetris", its fine however it needs something new, as if I wanted to play tetris, well there are thousands, I can see if this was just practice then its alright, if you want to make it better adding small options/changes could improve things, choices of music, block types ( like flashing etc. ) effects and things.
