Hey thanks for the input!
I agree the game is really hard, it took me like half an hour to beat it. They way you did it wasn't cheesing it, it was the only way to beat it because i didn't really think about the design too much and the 2 outer lanes became useless. At first the game did have colors in the middle lane but it was just literally impossible to beat and even if the colors in the outer lane gave more points it'd be impossible to reach them at high speeds. The ideal solution would be introducing a mechanic to be able to move through all 5 rails at high speed (maybe control the car with the numbers 1-5 and just teleport the car instantly to the lane) because i really wanted to focus on the sensation of speed (with the music and the colors moving really fast) so just making the colors slower wouldn't work, i'd have to put more thought into it, maybe i'll improve this concept in the future.
