Yeah, I've heard the coin collection and jumping sound effect whenever I move with it on. It's occurred on both the Itch version (which I just tested on after this happened) and the Steam version (the one I was originally playing) So it might be my PC. But now that I've heard about other people experiencing the bug, I'm less certain about that. Thanks for the confirmation, though. I hope you'll be able to fix it sooner rather than later, I've seen the gameplay from other people and it is genuinely amazing.
