not to bad, but not to good either.
Why no rotation for the fruits? And different fruit forms ( just like the tetris blocks ;) )?
What turned me off most was the change of speed from slow to fast several times during the game.
The second down-side was, that during the spawning of a new fruit setup u could not see what was coming, just the next fruit setup. Meaning that the "see the next block" feature was useless for me because I always tended to look at it when i could not see the actual block.
However, keep it up ;)
