Really cute game
That looked more like a fly-swatter than a bat, though. Anywho, I found it to be a fairly fun game for a 26 year old, at least for awhile. For kids, it'd be even better indeed. I liked the feel of the control, and that there were walls so you couldn't get lost offscreen like so many basic "overhead driving" flash games let you... Might help the feel a BIT more if the walls bounced you off of them a bit when you run into them head-first, though.
Also, there really needs to be a replay feature once it tells you your final score. The window is sitting there saying I got 94,000, and the music is just going on forever. I could just select play from the rightclick menu, but then the music is going to double on itself, and that wouldn't be too fun for my brain. #;-}> Great job overall!
