Sorry about that, I accidentally deleted it 🤦. Thanks for looking!
There's a version hosted on my server at https://vmi1489186.contaboserver.net/static/sliding-puzzle/, I promise it's pretty much the same as the one that I submitted during the game jam! (I corrected a typo of "sucess", and added a transition I missed, for when you press the space bar when on the title screen)
