If you mark that file as "play in browser" then your game should be playable on browser so people don't have to download the file.

Thank you. I did, and it was technically playable, but the problem was that Itch wouldn't let the text scroll in browser, and I had written longer passages which were no longer visible. My other Itch games work in browser, so I can only assume it is a compatibility issue with Twine and Itch. If anyone knows why, I'm interested. My solution was to provide the link to p5js because I put it there so you can play it in browser.
