The thing is I fully support remaking the game. Adult games like this often advance in quality and mechanics as time goes on, so the game's a bit outdated compared to some of the current top games
That being said
First of all, if your game's any good, have confidence in it. Like I said, it's outdated compared to some of the top games. Other games have been in development for years, but they have a healthy fanbase and the quality of the game itself outshines anything dated in it.
Secondly, the bigger problem is that releases for this game are so few and far between that by the time it is fully remade and the dev starts making new content, it'll be out of date again and the dev will 'have' to start a whole NEW remake (and yes, I'm aware that there's a pretty hefty case that that is the intention)
all of this could be fixed, hypothetically, with a faster release schedule. Shut Up And Dance has a release schedule where it alternates between releasing a new chapter and remaking an old one, or if you really care about keeping up to date, just finish the game and apply all the new stuff to your next project.
I try my best not to assume a dev is trying to scam, so I'm speaking under the impression they aren't, so take this with a grain of salt
