Hello! I'm sorry that it hasn't been working well for you. I can't help but wonder if this is a wifi issue or a browser issue or maybe even an itch.io site outage issue (itch.io seems to go down a lot. I have no idea why.)
The images and audio not loading combined with the fact that the code shown in the error isnt actually my coding that I did, but rather chunks of renpy's base code makes me think the game just refuses to download properly for you. if it continues not to work I would try clearing out your cookies and maybe even using a different browser. I'm sorry for the trouble :( I hope your most recent attempt has been working
