ok...
Well, it's a Tetris clone. It's playable, and it's fine. But, it's nothing special. The world has 3287231507 Tetris clones, and this adds nothing new to the scene -- although I did like the bunny. Backgrounds would have helped a lot, though, maybe even ones that change with the levels. Also, sound is essential... really essential.
I'd also like to see a spacebar "drop" feature, so I don't have to keep pushing the down arrow once I've lined up my piece.
It's not bad, but there's a lot of room for improvement. Hope you work on it some more. Better yet, use your graphics and programming skills to make something new and different!
