Poor

Sorry
But this game stinks
At Easy you just have to put your paddel under the 1 Ball spawning point and you can't lose till the paddel goes mad.
In Hard some ball's just pass through the paddel whitout a reason

Not Bad

But you get some bugs after some replays. (White dot's in the middel of the screen, some level jump instant to the next.)

Nice concept

Work a little bit on the GUI and the general graphics and bäääm a damn good game. A level select option would be nice. Hmm and clean the start screen a little it's overladed.
Btw advertising and the game should have the same design.
