Yea, I figured out the hard way that you cant go into those blue spaces on the left and right sides, they bring your score back down to zero. As for tips, if he stops hes going to do a special move, either the rocket, bomb, pole, or teleport.
Rocket: move your mouse in a circle
Bomb: go into the corner of the screen furthest away
Pole: same as bomb
Teleport: Put the mouse in the middle of the screen, he usually comes from a different side and jumps immediatly.
And for general gameplay just keep the mouse on the other side of the screen and move around him as he jumps to the newest opposite side.
dont understand it, its not in englsih.
you just click the link button (it looks like japanese characters; the first one) and you try to keep the arrow (cursor) away from the lil monster thing and make sure you dont go outside the box (the blue line things keep you safe but your score drops to 0) the creature is also armed with a bomb, rocket, what-can-be-described-as-a-2x4-cement-block, etc. have fun!
