W to accelerate S to decelerate R to reset car C to see collision sprite (for debuging) A and D to steer Space for nitroas
Man, collision detection is hard, especially on games like this where you have to move in different directions. It may seem hard to notice, but nitro actually makes you go 25% faster (500 is 25% more than 400) For Virus physics, set topRegularSpeed to 1, set topNitroSpeed to 75, and set nitroAccel to 3.
