Yes. It's still pong, no matter how fancy, but I do like the sandbox mode. (Runs fine on X3100.)
Aaaah, I love this game, simple but smart. Also nice "ambiance"
Obviously the developer of this game is going to rename it and make it better (just emailed him today).
If you cannot find it on the net, email the developer at
plasmapong.com and he will very happily send you the links to download Plasma Pong 1.3c (I asked for Mac and he sent me a PPC and Intel versions).
Really looking forward for the next version
