So after a bit of additional testing multiple games, the save functionality and loading between sessions now works perfectly, which I thank you kindly for. One point of concern is that because of how itch.io is set up, I’m pretty sure there is no way to declare an alternative link to the uploaded game (I think, anyway), and it can only be run from the “default” folder. Attempting to insert a different folder just results in no games being found when loading the player, since normally it would expect to be pointed to any alternate folders as part of the URL.
Playing multiple games like this, your browser would still think you were playing “default” even if you switched to an entirely different game, and it loads up the saves from the other games you would have played as well. Please correct me if I’m wrong in my understanding of this.
