I'm only getting the message "AccessDeniedAccess denied."
Weird, where do you encounter such a error? In the main page? Inside the browser game runtime? On the downloads page? It is hard to debug that when I have next to no info to work from.
Edit1: I don’t find any match where such string would be in the whole codebase. Perhaps it might be from Itch.io’s hosting end as I have personally seen some access shortages (on my hardened Firefox in Canada) outside the dedicated app online in the past few weeks.
Edit2: After lurking some to see which platform you are on (Apple macOS), I am not really that surprised (definitely not pleased, over Apple walled garden that is). While I currently don’t know how to fix such macOS web runtime query yet, I will take a look into such as to to make it work for macOS hopefully soon (likely but not guaranteed to make a properly signed macOS native-ish port of such once I reach the Godot phase). Either way, your comment is very well appreciated.
