Which jump are you exactly talking about? Do you mean that one with the shortcut where u have to take a really slow path if you miss it? That one is a bit difficult but using Laplace might make it a bit easier because of his special move. The grass definitely doesn't work well with lower end hardware, I've tried lowering the render distance a bit to see if that would help and it doesn't do much. I'll try to see if there's anything else I can do about it. That glitch on the level clear screen is also very strange, I'm certain that's also hardware related because there used to be a similar glitch on the UI's display that only happened to some players. I think I might know how to get that fixed but it's difficult for me to determine because it doesn't happen for me. Thanks so much for playing and posting footage!
