Use the arrow keys to move, and
SPACE key for everything else.
During the race, you can pick up powerups to get an advantage. There is also a manual firecracker item used with SPACE during the race. The firecracker can slow down opponents, and cause them to fall in the water if done at the right time. Your opponents are all larger and can stun and slow you. When you are stunned, you can also fall so be careful.
Note: After the main game there is an ?infinite? race mode where the opponent keeps getting faster. It should become impossible at some level, but we?ll see how high the records go.
