WARNING: Many hours and/or days of wasted time await you.
It's an odd game, where the object is to hit a guy innocently standing in the park with your bike, then launch him as far as possible.
Conveniently, everything in the game is in english
EXCEPT the instructions.
Tips:
You can teleport your charecter into the air to hit the guy by clicking when the name "AERIAL" is red or blue.
Sometimes you are able to preform a "special" move when the guy hits one of the charecters by clicking anywhere when you see "special" flash on the screen and hear a beeping noise.
Avoid having the guy hit the two men charecters, the girl with long, purple hair, and the girl with glasses. they will do various things to make the game harder for you, and the girl with glasses will stop the guy completely. However, sometimes you can perform a special move with that girl.
My record is 6,199.62 meters.
