Sorry if this has already been posted, I tried to search but came up with a bazillion results
If you like Pong and want a new (really cool) twist to it, then just download and install. You might want to read instructions, its a little different than what you would think.
If you can't download it (it took me a few tries to complete it) I can send you the setup.exe.
Not only is the pong cool, you can also just play around with the "plasma" in various ways . Enjoy.
