Keyhack Q add money, W add fuel.
Your task in this third part of funny upgrade game (Potty Racers 3.4, v.5.6) is to build a flying machine and try to drop of the cliff as far as possible.
Hit the accelerator and go full speed with mad over steer around the corners. Although that certainly is the most spectacular approach, it is also the most suicidal.
Better would probably be to use your brake once in a while, as long as you don`t go granny style.
Press RIGHT ARROW KEY to push your porta potty down hill. Use LEFT and RIGHT ARROW KEYS in the air to keep balance. Use UP and DOWN ARROW KEYS to retract/deploy wheels. And press SPACEBAR to use engine (once purchased). Use the earned cash to buy upgrades for your vehicle. Have fun!
