Nanaca CRASH!! This is a pretty fun game. The person who showed it to me had this to say:
It doesn't take long to get the nuances to this game down. The instructions are in Japanese but the basics are easy to figure out. Basically you click to select the angle of attack, and hold it down to determine the strength. Once airborne, the different characters you crash into do different things...some slow you down, change your angle or give you a boost. You also have some power attacks...the AERIAL indicator in the upper left wll flash red or blue when the character is a set height off the ground. Red Aerial attacks boost the victim forward and up, while down angles your character down. Once you've hit a few boosts in a row, you get access to a special power...click fast while it on screen and you get a super duper mega boost. It's not as complicated as I'm making it sound...just try it.
Right now my high score is 1148.28, but other people I know have gotten over 5k.
