I feel obligated to ask, what's with the trend of early releases on Itch graduating to Steam exclusivity? No offense or anything, I just prefer having the standalone backup and it strikes me as odd when a standalone exists but ends up abandoned.
I'd put the full version here too, but I think itch has some issues and you can't have both a free and a paid version of the game at the same time on the page. I will try to bring it here too but as I said with the GoG plans too, I am simply busy 24/7 these days to be able to handle anything more than I currently am.
