Hello, I've been experiencing this bug with the player one controls , no matter what  red player goes right, I can't  control it.

I've tried out other uploads apart from tis itch.io one, 

I've tried rebinding the more right to 'f' , still goes right nonstop. 

Pressing 'go left' does not override, still going right.

using opera, ie doesn't support unity webgl.

Ive seen this twice before. In both cases they had a controller of some sort plugged in, that was giving the command

could be gamepad, or steering wheel

thanks for the input! tried out with firefox, didn't have the same inconvenience. Weird that a plugged in game controller can have such an influence.
