Tetris is tetris..
Not much you can really do with it, but change the look of it. I liked it overall, but then again I love tetris. :3 Nicely done.
Reviews for "Block Tetris"
meh
the concept is interesting but its quite slow paced and unrewarding. You at least could have added some music
Boring
Colors are bland and I don't care for the bird chirping BGM
Try to put it on facebook, Its just as fun as mafia wars and farmville.
Decent
If the camera would have been moved back so you can see the ground it would have been better, still a good clone though
