A bit of an overdone bore.
Sorry man, but the game with a bit of a bore.
It didn't hold my attention long; maybe I missed something, but is the premise really just dodge the grapes?
Sometimes simplicity in a game works (such as falldown on the TI83 when you're reallllly bored in calculus), but other times, as in a flash game that seems promising or at least witty, it can be a let down.
Please don't fall into the trap of making a high-score table a saving grace; generally successful games use it to make their games more successful.
Maybe if you added more gameplay elements, such as a story/plot, something else to do than dodge grapes, or did something like make it a compliation of minigames it'd be more interesting.
However, definitely not as bad as some submissions.
