Yes, it's done this every time I've tried playing your game, on two different computers from a clean install. One ran Windows 10, the other Windows 11. I've tried the regular ZIP file, and I've tried installing from the itch app. Guess I'm just cursed.
Yeah, sorry I can't help. I'm not aware of anyone else having that issue, it does sound like an input issue on your side though. You said you ran it on two different computers, were you using the same keyboard, or did you possibly have a controller plugged in?
actually, other question just to clarify - you said this happens when you load a save? like you can start a new game and play fine, but if you save and reload that's when you have the problem? or does that happen in any game state?
Any game state. No other game or program registers an input like this. I want to say same peripherals between pcs? Two keyboards, a gamepad, and a mouse. All work as designed with no weird behavior, and have up to date software.
