Any way to sync between devices more seamlessly?

I use Twine on three devices: a personal workstation at home, a personal laptop when I'm travelling and at my work laptop (the web version). To work on the same project across decices I've been just exporting an html, uploading it to my google drive, then kind of continue where I left off in whichever machine I want.

And I get it, Twine is open source (and I love it for that), a cloud based proprietary syncing feature would not make sense. I get that. But just the hassle of importing files over and over everyday, creating new projects on each machine that I then have to manually delete, sometimes inadvertently deleting the main one by accident, has me in want of a more seamless solution. Additionally I struggle with just the clutter of an extra layer of work to get started writing when I have ADHD and getting started with something is the thing I most struggle with.

I use this tool called Syncthing to sync my Obsidian vault and I tried using it for syncing my Twine games too, but again it's not very seamless since it creates multiple copies and then I have to manually import it to Twine on every machine again.

Has anyone found a way to solve this?
