Unfortunately no, it's not coming to Gog. We proposed our game to Gog and it has been refused for being too "niche".
Sorry to hear that, but yes, their "curation" is sometimes a bit quirky :|.
To be honest I was already planning to buy it if it came here, so I'm definitely going to vote for it on the wishlist if you say that helps.
Edit: And since there was no wishlist entry for it (come on guys, really??? Nobody created one?), I've created one here
