Bug fixed! Now you can get on and off the board freely!
A strange craft that you can drive it when you stand on it. I call it a flying board. Press alt (or any stunt key you defined) to jump on it and surf the air!
I replace the motorbicycle in the black market with this flying board.
Actually it's moded based on the hovercraft. So you're not really flying, it just looks like that.
See more details in readme.
