I'll try my best to see if I can fix this issue, but there isn't a whole lot I can do (at least not that I can think of,) it's simply due to how floating point numbers work, they are only so accurate.
although it starts off hard it gets much easier once you get enough money to get a new car. my only complaint is that turning is pretty slow, but the car mechanics are really nice and i love the artstyle. very fun running over zombies lol
i love how the difficulty is somewhat synced with the intensity of the music, starts off pretty nice calm and easy then before you know it your phone just has cancer or something
