Were you trying to load an old save?
There wasn't even an old save to load, it had been so long since I played lol Just two html files in the folder, the most recent one, and an old one from... 2021, I think, named "bad ritual" instead of index, and the folder was 1.8mb even after taking out the "bad ritual", but after taking it all out and installing again it's at 1.1mb, that why I'm betting that it was caused by some type of conflict or something.
H'm the only thing I can think is that the way. Because the itch app is at its best installing like GAME game files, and I find it behaves a little funny around htmls since they're not actually an installation (everything happens in your browser, no files are created, the html is just downloaded and stored in the browser). Try playing it from the launch button?
I'm so sorry, I think I didn't explain right, I fixed the bug and managed to play through it all (amazing as always btw, Siruud worried was *chef's kiss*) 😅 both browser and app works fine and without the bug now! I was just trying to point out I think caused it. I'm really sorry for not making it clearer that I solved it 😥 thank you for all and really, really sorry for the confusion!
