I saw my cousin playing the game and could see she was clearly struggling with the controls as she isn't familiar with how to play with the arrows on the keyboard. I then thought, there has to be an easier way of playing the game and having fun at the same time, right? So I thought about it a lot and came up with a possible suggestion that could help people play the game more easily.
The one suggestion I have is using the mouse button.
Why not have the mouse as an optional controller itself? The left click as accelerator, the right click as reverse, and maneuvering the mouse to left and right in accordance to the direction the kart should turn, but keeping the space button at the same time.
I'm no programmer, but I think it may help the user to be able to chose their preferred controls. What do you think?
