Use the ARROW KEYS to avoid the cars and the jet. Every ??? seconds your world will change. When you are in the Underworld, your keys drive the opposite way. You can create a Paradox between worlds when you hit an Underworld car and it teleports you back to the Overworld. (It's hard to explain but it's my only justification to a glitch that is in the game.) There is a secret... It may be usefull, but it may be not...
