Looks exactly like RPGmaker game but very bad performance-wise. Why do it in unity to begin with?
Well, engine's free for a start, does 2D and 3D equally well if you know what you're doing... Problem is, performance improvements don't appear to have been looked at, as opposed to what's usually pressured for in a Patreon release (MOAR CONTENT... NAOW!), sooo... That's my guess.
Also, yeah,
could make it in RPG Maker... If you had a version of RPG Maker
and were familiar enough to get around its limitations (Some of which are annoying as hell or unintuitive to work with), whereas, with something more open, while you don't have basics already done for you, elements are easy enough to set up that you can quickly throw something together if you know what you're doing, and re-use code elements for stuff that works exactly the same.
So... There's good reasons to use Unity, not least of which is "It's free." But the tradeoff is that it's also easier to code things in a resource-hoggy way.
Is female start not an option?
Unfortunately, not that I could see.
That's more on the decision to have full-screen sex animations, which add an entire new asset set you need to introduce (or have a whole bunch of "this content doesn't exist yet" markers.) Time will tell if that comes through. In all honesty, I'd prefer they work on performance before trying to add more stuff, make what they
have work better, but, as mentioned, folks get antsy if your update doesn't have MOAR CONTENT.
