I also got to use exclusive or in a similar occasion for an application I
wrote some time ago (a Palm 3d engine where I had to overlap precalculated
segments for the polygons' edges), and such solution was actally suggested
to me by a friend who has a lot more experience than I do on such stuff.. So
I guess thar EORing is pretty standard in this case, and you can feel
confidet it's a strong solution! :)
(now that I've said that, I'm sure several hundred better solutions will pop
up shortly.. ;)

The helicopter/cave game came to my mind just as soon as I tried the binary!
The paddle gama idea also looks good to me, so you may even think of a game
that implements both ideas, maybe on alternate levels.. But if you want to
keep the game simple and choose only one game style, the latter I prefer!
Looking forward to see what comes out of it..!
