Ooh, mouse controls for the menu! Well... I must admit that when I started designing the menus, I had to decide whether they’d support a mouse, or be keyboard/gamepad only.
I looked at games like Sonic Mania and Slipstream (both don’t have mouse support) so I went with that same approach.
If I ever want to change that, I’d have to rethink how it would work intuitively.
About the steering controls: There is a slider in the options menu called “Steering Speed.”
Lowering it makes the car respond more gradually to your input — but it doesn’t increase turn speed the longer you hold the key.
Maybe I could add an additional slider to control that behavior.
Although I must admit: slower steering input might be a disadvantage in later races, where quick reflexes are key to staying alive.
