Confusing and unfun.
There's no indication of how holding the spacebar down changes the way my fruit is thrown, so it's trial and error to get it right. And then, it turns out that apparently it's impossible to win even if you hit him in the head... at least, until you choose the pumpkin. But the goal you're given is vague ("get him off the stage"), the only way to do it is never alluded to ("kill him"), and the interface is so crappy, you can't tell if you're getting closer or farther from your goal.
P.S. The last person I know of to misspell tomato was Dan Quayle.
