I found it very challenging. I got through the first level but couldn't get through the others.
This game mostly made me feel out of control, but the brief moments where I felt in control made me feel accomplished.
My favorite part was how difficult it managed to be while having a simple control scheme. It made success feel obtainable, even though I was struggling. My least favorite part was how fast it was. When I was in control going fast felt very cool, but as soon as I started swerving the speed made me feel like giving up. I wanted to be able to slow myself down around turns or when I got too fast. I think having some sort of mechanic that slows the bike down when the player is swerving back and forth a lot, while speeding the bike up at the same rate it is now if the player is making more controlled movement. This might help the speed feel fun when the player is successful but not so punishing when I'm spinning out of control.
I played this on my desktop, but I feel like I would like playing it on mobile devices the best.
Overall I enjoyed playing this game, thank you for sharing it!
