Thanks for the fededback! As for #1, I've tweaked the game optimization for a 40fps increase and will post and updated version later today.
2. This will be added in the future.
3.It's meant to be tricky! I've taken feedback with people finding the jumps hard, and increased the top speed with about 5kmh, making it easier to land jumps. I've also tweaked the steering rate so there's less of a delay.
Appreciate the feedback! Let me know if it feels better to play after the new version is out :)
