I would recommend holding off until 2025 when you see this game randomly pop up in the latest section with a "Complete" tag on it. If it ever gets finished mind you, we are nearing four years of development and it still has less sexual content, which is what 100% of all people are playing it for, than most Patreon released projects do after two updates. Shit, most games have more content in one update than this thing has had in its entire existence, and I don't actually think it's due to the developers trying to milk its patreon of all it can. That may have been the result, but I'd say it's more due to gross incompetence than it is anything else.
The people making it have no idea how to design a game. They seem to be lock step focused on this idea that the game has to be developed on a particular course, and that it has to feature "gameplay", and that specific plot events must occur. Noble sentiments, but in reality this just limits what they can create. This style of development might work for a professional project, but a professional project has dozens to hundreds of people working on it, with multiple people in charge of particular aspects, and are built in an asynchronous style that allows for milestones to be met consistently that do not wholly rely on other development branches to have completely their sections. It might have worked if they didn't have to release content on a semi regular basis to keep people playing. It only works for professional game development because you're releasing a primarily completed project all at once. They should be focused on building content for individual plot lines instead of building entire plot lines. Fans want Hermione? Focus on her for an update. Then move to another character and so and so forth. Then once everything reaches a certain point you spend an update weaving that together as a chapter. More games should be looking to Summertime Saga as an example of how to do things. Not necessarily the speed at which DC and company works on the game, but how they focus on individual characters per update instead of the entire game.
Unfortunately they're never going to learn their lesson because Patreon encourages incompetent buffoonery by allowing funding to go through regardless of whether or not a project shows progress.
