I remember playing a web racing game in which you raced other cars (NPC's) that had polygonal-ish graphics and you could do crazy stunts by pressing the "space" button and if you landed them you had a speed boost. You also could destroy other cars by ramming into them fast enough and that when you ran into walls/obstacles or when you messed-up your stunts your car got damaged and could blow up (your car would flash white and then turned vlack when it did). I also remember that you unlocked cars as you completed levels, and that you could drive a formula 1-ish orange car, a beige safari-ish car, a blue/black vintage car (like the fancy old cars that you sometimes see in cartoons) and many others (all of which had different stats like speed, resistance. The checkpoints that were on the ground were rectangular arcs and there were repair stations that were in the air were in a weird ocogonal shape. I remember that there were two of them and it's driving me crazy not knowing the name of that game, so if anyone knows what that game is please tell me! XOXO
