The big issue is that many of us have backed projects at one point in time or another. It becomes like a ponzi scheme in the sense that eventually, one group of active backers will be backing for 5-6 months of no content and then the developer will announce that they're giving up. They're left "holding the bag" metaphorically. At the 5$ rate, that's 30$ of money thrown after a non-existent release cycle. Many of us get burned by this once or twice, and then we never back an incomplete project again. As stated before, with 4 projects he works on, owns, or assists with, that's 1 weekend a month the project your backing gets any attention. Competitors in the market will have the same 5$ level, and one project, you're essentially buying their spare weekend time and getting three to four times as much "return" as if you invested in one of Alorth's projects. While is quality is better than most Ren'Py, you could have also put your 5$ into a project like wildlife, which is superior-still, on a technical execution level. Alorth's work has value primarily because of the IP aspects -- character, personality, setting. Not visual fidelity, even if he is excellent at it. While many of us don't contribute, it doesn't prevent us from seeing and pointing out mismanagement in a respectful or reasonable way.
Frankly, I'd be okay if the game got "story" updates, with IOU placeholders like draft renders or storyboarding for renders and animations. I bet a lot of people would be alright with that. In fact, I think this would give Alorth the ability to jump between which scenes he felt like focusing on which could help with burnout. He wouldn't have to drill down on a blowjob scene if he wasn't in a blowjob scene mood, just because the blowjob happened to be the current step in a story path he was working on. He could skip over that and just leave behind a draft render of some dick sucking to revisit later.
I was a game dev, but I failed out of the industry because I let mood and "avoiding burnout" become my excuses to be late on projects. If his dream is to be a full time game developer as his donation sites say, he's going to have to learn more self-discipline then I had. The industry is NOT kind. Mick Gordon did much the same with his doom music fiasco, and despite the quality of his music and the community's love for it, he might not ever get to do another doom contract because of his fickle behavior on the last project.
