I see, if the jumping weirdness is intentional and falls in line with your vision for the game that's fine then- once you know about it it's pretty easy to work with.
The bounce changes feel great by the way! Went into my completed save and bounced around on a bunch of the beetles, and it felt a lot more controllable for the first few bounces. Then tried to do my old (stupid) strat for getting into Locked Room Mystery, which involved bouncing on a beetle over the spikes while setting up a charge bounce to get in, and it was still very difficult and precise since I had to bounce in place for a while to line up the shot. Feels like it's worked perfectly.
