Imagine Breakout, but instead of just moving the paddle, you actually play as it.
The world of Breakout clones is a large and messy one. Especially with all those broken bricks and dropped balls laying just under tha bottom of the screen. Where do you think they go? Have you ever thought of that? It's messy!
Now, this game doesn't attempt to clean up anything, but it does attempt - and largely succeeds in - frustrating you blind. The object is to break all the bricks and to do that in less than the time limit.
The problem is, you bounce the ball. On your head. You aim by strategically jumping and moving left or right at just the right angle to hit the bricks you're after.
This simple task is complicated by the insanely fast speed of everything and the incredibly unspecific method of aiming employed in the game. With the proper care, this can be ever so slightly tamed by correctly timed keypresses. Practice makes perfect - well, less than completely horrible, anyway.
