Yeah, you are right. The biggest thing is an underlying issue with the movement solution I used where the player is a capsule instead of a cylinder with a flat base and you easily slide off platforms if walking too close to the edge. There's a bit of coyote time to allow jumping after sliding off ground but it's still pretty noticeable and annoying. I put this all very quickly, game jam style, and didn't manage to properly fix that issue, sorry for the frustration!
Thanks a lot for playing and leaving a comment, appreciate it!
