This is pretty cool although a bit hard on the eyes :D
I only played one round but I reached 1060km.
I'm not sure how exactly your fuel works, but it was looking pretty good, almost full when all of a sudden I got a game over.
Thank you for your feedback!! I noticed it can get pretty hard on the eyes, especially when it gets pretty fast :s By the way, good score!!
The fuel is constantly falling, and the squares fill it up, so maybe you were collecting the squares in the beginning and didn't collect them after a while? Also, the circles remove your fuel greatly, which could cause a sudden game over. Do tell me if there was a bug though! Thanks again :D
