The game is pretty self-explanatory... move the mouse to avoid the "meteors". If you get hit by one, well, you explode... just avoid the "meteors" at all costs, and you should be fine. Don't forget to check the score when you explode... have fun! (Lag may cause inaccurate score results) (Leave comments below if you have any suggestions/bugs.)
