I played this previously but when trying to play it again it said it couldn't load project data and asked if a .pck file was missing? IDK what it was on about but I thought you should be made aware.
I'm not sure because I've never seen that happen before, even when it was my own first time uploading a web game made with godot. My only guess is that maybe it has something to do with your export settings? I was able to play it the first time, I just couldn't go back to it the second.
