1 x makes you win, 1 x makes you loose, other x's subtract points. 0 is the global it's almost impossible to beat! BTW It's the worlds HARDEST game! Arrow keys to move. If you loose comes or you win you can still play! You can press space to set the global high if it's higher than the one now! Don't worry, if the screen says you win and then you loose, you've won because that's what happened first.
I'll admit: I kind of used a little bit of the tutorial for these kind of games!
