No,this is not about a bike with a happy face on it.
This is a game called Happy wheels,where there's blood,lots of it.
So,here are the controls
Z= Eject: You get out of your vehicle(i like this feature)
Up=Go forward
Down= Reverse
Left= Lean left
Right= Lean right (No Awsd)
Space=Once you eject you can grab onto stuff(Dont grab on things when your falling at great speed)/Use your special ability
Ctrl= If you are with 2 people(same vehicle like the dad) You launch the person than yourself/Move your jets if you're the old man
Shift= Same goes as above,move you're jets as the old man
Play the game here!
