Are you subbed to his Patreon? And if so, do you think any of your donations over the last 5 years has built towards a release of any amount of content whatsoever?
Because 5 years is a really long fucking time, and as much as I like the game and think it has potential, it's ultimately a VN with some simplistic exploration and turn based combat mechanics.
I think someone could hand this guy a million dollars and that wouldn't move the needle one way or the other towards him making an update.
Ultimately he has to choose to do this shit and unless he's been remaking the game with a much larger scope he hasn't been doing very much since writing a sex scene or two accompanied by a CG, especially with his minimalistic art style should take months, max, not half a decade.
I consider every artists that hide their art or games behind patreon walls as a scammy salesman, meaning I don't care about their existence, if I don't see their produced art anymore. That's the only thing I care about patreon and such. I dunno why people like you like to count other people's money if the artists don't hide anything behind paywalls. You can also wonder if Meandraco's mother still gives him an allowance and how much of it goes to creating monster porn.
Dwarf fortress took 22 years to release official graphical tiles and it's still in development. You can say: "Dwarf fortress is a very complex and wide game, how can you compare it to a simple VN"? Well, I'll answer: Both games are passion projects, dwarf fortress has been developed by two people, Teraurge has been done by one, those people still need to work to get food, pay taxes and etc, or do you consider 380 euros for Meandraco enough to quit his main work?
Do you know why most VN's stay in a demo status for years? Have you considered how hard for one person to do all the work small indie game companies do? Or do you think the code writes itself in a program or all the art, backstage, CG have been done by AI already? It takes their precious time, doing monotonous things over and over. Most games will never see the end credits, most die when the single developer quits by different reasons. Million dollars won't work here, the artist won't spend it on hiring a crew, he will spend it on fixing the roof or buying themselves a better tablet. The pacing will stay the same, that's what you don't get. You can hate how slow he makes the game, but nothing will change on his side, he doesn't care, since, again, that's his passion project. He is not building an Ark for you or anyone else, there is no flood coming to drown us, so why should he move his pen faster? He doesn't have an obligation to even release it to public. I doubt you would have heard about this game if it wasn't shared here. And so you should stop caring about moving his pen faster. He won't, not for you, not for any other. It's been 5 years, yes, so come to terms with it already, you could find something better to do than criticizing another "Abandoned" game.
