Bounce a little 3d cube around the screen, sending off showers of sparks when you hit the edges. Its Pong, but on Steroids, and if thats illegal in your country, then think of it as a classic arcade game thats eaten a LOT of steaks.
Loads of powerups... big bat, double ball, super speed, disruptors, extra points and Mr Freeze make game play challenging and add a nice level of variation.
Three skill levels, and most fun a two player option where you can battle for victory and glory.
Id say amazing ground breaking physics, but I mean seriously its a bouncing cube, but it bounces really really well.
