game is hard but a controller controls makes it a tad bit easier
if you do have a controller use it
Here are the controls (for xbox and ds4/ps4)
left stick: turn left or right
right stick: left is reverse, right is accelerate
A/cross button : pause / cancel
X/square button : select / ok / confirm
give it a chance you'll find it easier
the game is pretty broken since there are some part of the maps that you can just take it as a shortcut as long as you go through the lap rings
don't try to use the keyboard cause it makes it impossible to control
