Heads up this build hard crashed my PC upon closing.
Some general feedback: I'd add a bit tighter controls or less "slide" on the edges, and change the walls to be a contrast with the background white walls+white background = player frustration. I think the pace of the track is solid, and the wall distance is good, but the sliding results in less precise controls and less feeling like you're getting "better" each time you play. If you want the difficulty to be high, I'd instead put more hazards and speed up the track while really nailing down a tight control feel. Then if a player screws up it's an incentive to get better versus a "this game isn't fair" feeling. Good game jam game! Definitely keep developing it!
