Pretty sure the creator has decided to make the game for Patreons only. Version 9.2 is avaliable on Patreon
I saw, but that's the last patch and ZERO real updates/posts since outside of some advert for another game.
Either post something on at least a semi-regular basis to at least let ppl know you're alive, or quit and save everyone the trouble. I hate to sound harsh, but that's the least they can do if ppl invest in a project and get no return on investment or have reason to lose confidence in the dev for a lack of communication.
