Thank you very much! Though I am very pleased with how the bike controls, I admit that it might take some time to get used to. I invested a big chunk of my dev time into the bike controls, so much in fact, that I probably got very used to it while testing and didn't really anticipate the players' struggle.
A tutorial-esque additional race track was literally the next thing on my ToDo-List, but my time kind of ran out. The prolonged submission timeline would have probably been enough, but I had other obligations... Maybe after the rating period!
