Maybe? If I'm not mistaken, you can download the game in the Itch.io app, but that's basically just a local copy of the web version.
Given the fact that so many people have been asking for a true downloadable version of the game, I'll probably get around to it at some point. Also, I'm about 50% sure there will be another "mainline entry" at some point. Not 100% sure, and it's probably going to take a while if it does happen (I keep saying this about all my games, but it's true.)
P.S. My Mastodon profile is probably the best place to check if you want to view updates about my projects.
