VERY cool game. It's a spin on Pong, obviously, but with lots of sparkly colors and explosions. I can't imagine playing this while high.
Plasma Pong
What I recommend doing is this:
Play Single player twice.
Fool in sandbox for an hour.
Play single player again.
Kick friends ass in multiplayer.
Quit game and/or uninstall.
It's good for a time waster of sorts. I personally got to level 29 then lost.
