Have you already downloaded it? I noticed an inconvenience. The jump meter resets to lowest upon transitions. I'm uploading an updated file without that problem. If it bothers you download it again.
EDIT: Re-Reuploading to fix a minor visual bug.

Hey AlphaBetaGamer. This shouldn't be happening, it's either a bug or you're doing it incorrectly. You must hold the left mouse button to charge the jump and the right to uncharge it and it stays put. Then, when you tap you jump as high as you've set it. If you hold she will still charge a high jump. It's in the description but maybe it's not clear enough. Have you done all this and it doesn't work? If yes, I'll take a look again.
