i guess it's just some healthy competition.
so if you wanna play and too lazy to read the instructions:
the black box you first see = you, control by the mouse
other flying black boxes = good, get it =)
flying red boxes = game over
black dots = your friend
red dots = not your friend
enjoy and tell me what is your highest.
p.s. the music is a little annoying, you can turn it off by clicking the "music" word after you lose, which you will!!! LOL jk ;P
