Hey! Thanks for reporting. This was an issue with the SharedArrayBuffer setting on Itch.io, which is required for Godot web exports. I've just enabled it, so it should be fixed now. Sorry about that, and let me know if it works!
It works now. I just beat it. It is a good game and I urge you to add a few more tags such as Horror ones so that people can actually find it in search easier.
I think tags such as “cute” or “stealth” would help as well.
