The author’s own description probably does this game best: This is a simple and but annoying little game. The object of the game is to move the ball around and prevent the ball from reaching the top of the screen. Use your Arrow Keys to control the ball....The level increases every 5 seconds, and it gets faster and faster until you lose the game. 

This is very simple and you’ll probably get tired of it quickly.  Ultimately though it will be over quickly as once it speeds up you almost have to guess where the next hole will be to drop through.  One tip is that the holes tend to move left right left.

The music reminds me of something that would be in an anime cartoon.  Depending on whether that’s your thing it might be annoying.  Ultimately this game is worth about three minutes of fun and you’ll probably only play it once or twice.
