Thanks for taking a time to play and leave feedback!
Maybe add some scenery to generate near the track so it's not just train tracks in an endless sea of green.
Totaly agree! I have a plan to rework background completely (currently it's just a shader), but it's constantly getting deprioritized in my head :P I'll it to the roadmap and publish on game page so I'll be more comitted to it.
An updated UI would be good as well, maybe have the speed change size as you speed up and start flashing as a warning when you're going dangerously fast.
Great idea, didn't think of that. Will research how others games apply similar behaviour and will add it, should be relatively easy.
