I get that the dev is on vacation and whatever else but he needs to stop with the promises of releasing on a certain date then ghosting when the time comes. If he expects funding and support from his work on this project, at least just be more open about what's going on. I can see he set his subscribestar to vacation mode and at least that is something but if you expect to continue making a living off your work on this game, give us more frequent updates about what's going on here and subscribestar, be honest and open about the actual issues your facing. If bugs are breaking the game so much your hesitant to release it and/or your burnt out on the games creation, at least tell us so. Id be way more forgiving of that than the guy just being pretty much silent altogether.
Also a ahead of time response since I already know how people are going to respond, stop white-knighting porn creators.
