I see, maybe I turn down the speed then for easy and normal and leave it like this for hard.
Also thanks I take that as a positive thing xD
Sorry I don't fully understand what you mean. If you talking about controller support and settings: The game already has a setting to rebind controls for keyboard and controllers. The controller option only shows up if a controller is detected, i think, so you may have missed it because of that. I only tested ps3 controllers but other like xbox controllers should also work, just don't have one to test it out myself.
Update: I added a option to slow boulder that will show up after losing the race for certain amount of times. It is include in the new patch!
