Creepy game, just unsettling enough, nice job. The van sprite is really nice, looks like it was a lot of work. I really liked the headlight effects too, the way the trees have multiple shadows is nice (its like we have multiple sources) and the subtle red light behind.
Managed to only find four areas before running out of fuel and I feel like I explored all the road and even did a fair bit of off-roading - is there another section of road that is not connected to the starting path? Also, minor bug, but the gameover screen assumes you died from failing the headlight reaction test and not running out of fuel.
