Changes: -Switched the cars collision system, uses a really similar method to the tile scrolling mario tutorial. This is far more consistent for speeds, and with checking for collisions before turning the car, avoids the car getting trapped on walls. -Fixed enemy sizes. STUFF FOR IMPROVING - Failed to change the bullet particles. Please keep particles and important game mechanics is different sprites, messing up one can mess up the other. - Please don't use abreviations unless obvious (ex: dir, vel, ect.)
