WASD/arrow key controls. The game won't start until 2 people are on. You can play with yourself, or spectate yourself. Wait 2 seconds before connecting with a friend, there's a 2 second slot delay before playing. DISCLAIMER - as soon as the race starts, go. It may appear as you are behind or ahead, but your time is measured, so latency may make it look different. The chances of someone else being on at the same time as you are minuscule, so ask a friend to play with you for the best chance of playing.
I do not own the car art used in this game. it is owned by Micro Pico Racers on steam.
