As of right now, I have no idea when the ending will be done, since I've only really finished act 2 and still have to start and finish act 3/ the epilogue too.
But I'm definitely over halfway with this project and can start to see a finish line. As for releasing/selling here on itch, I'd love to when i finish the game, but Itch still hasn't sorted out adult content properly. I can't even accept donations here or I'll most likely be delisted.
