I don't know if I'm just missing something, but is there a way to do short jumps? Because one of the level keys -- I had to look up where it was, because I was completely unable to find it on my own -- is somewhere that's too high to get by just walking, but too low to get by normal jumping; especially when I'd unlocked purrks, which I'd been worried about since it was an issue in the original game. However, unlike in the original game, I haven't been able to get to half-elevations like this by doing essentially a controlled fall; so I'm worried that I'm forever locked out of what had been my favourite level in the original game, unless I uninstall then reinstall the game, since there doesn't seem to be any option to remove purrks.
