The main problem is the time & energy it takes to make this might result in burn out. Biannual updates that consist of 2-3 story beats per main love interest is a glacial pace for normal game development. This is a visual novel stapled onto the RPGMaker engine that's been in development for 3 years, and the recollection room is only half full.
Its gameplay is half-baked at best, and the world is generally dull and empty outside of the various character driven quests. There's no real gameplay that justifies an open world setting, when it's easier to just jump, Ren'Py style, from location to location. It's a weird choice to use RPGMaker and pour time and energy creating the world and populating it with NPCs, when there's no mechanics to engage with.
This update, while really nice, is a warning sign to me. By year 4 a game like this should be wrapping up its main storylines. Given the trajectory of the story, there's no greater tension point than him and Leslie- every side story is going to feel a lot lower stakes than that one. Once it's resolved, it's pretty easy to assume there's no woman Jon can't seduce. It's very easy to write an ultimate showdown between him and the main antagonist and wrap the whole project up. That way, if the creators grow sick of it, they can put it down and use their built-up fan base to fuel their next project.
I swear, Western adult game devs don't seem to get that they in fact build fanbases that will follow them from project to project. There's no need to stretch things out for most of a decade. Japanese porn devs get it, IDK why Western devs don't.
