Pumpkin Push -- a Halloween-themed Time Waster

But it's not as simple as that. It's not just a Boulderdash clone with Halloween-skinned baddies and pumpkins for stones -- no, it's like some kind of fantastic mash-up of Boulderdash, Mega Man and Pac Man. In Pumpkin Push you play a plucky pumpkin-pushin' protagonist whose primary objective is to clean the world of various undead ghouls. Vampires, ghosts, robot-pumpkins... they're all here and waiting to be vanquished.

I don't know how big the game is, but there was even an end-boss at the end of the first world! This thing might prove be more than just a mere time-waster...! You can even play as a girl.

There's even a hint on the options/help screen that two people can play at once -- cooperative Mega Man style! -- but I couldn't find a way to activate it.
You should give this one a go. It's one of the better Flash games out there at the moment.
