I wonder why some dev uses this tool for the game's models. The result is only slightly better then drawing stick figures with Paint.
That's a matter of taste, I'd say.
If you're not into 3D anime style, then sure.
The range of quality and realism one can achieve with KK is quite large, though.
I'd say we're about upper average by "games using KK models" standards, judging by what I've seen from other games on itch.io.
It must be very quick to use and make some buck out of it.
It beats having to draw or model from scratch on your own, sure.
But unless you hit some nerve and reach 2K+/month (which we haven't), the return on investment in terms of time vs. money is still quite poor by western income standards.
It's also more time-consuming than you might think. Working with KK is lots and lots of fiddling and fighting with camera angles, FoV, lighting, offset issues, clipping issues and so on.
And that's just the posing part.
Regardless of what you might think of the art style, some of our character models took several weeks of work until we were happy enough with them, and from time to time small updates, new outfits, or custom variants are needed (and new characters, of course).
Using AI generation like Moonripple at least lets you do something else in the meantime, working with Koikatsu is non-stop active tedious work. You can't even tab out during animation recordings, because that breaks anti-aliasing.
No repeatables on the new girl? After the first scene with her, the Park is just grayed out now.
2 repeatables in 0.5.5, 2nd event + 3rd repeatable in upcoming update 0.6.
Game is not opening in joiplay (Android ) any words to suggest what't do.
What version of Joiplay did you try?
The game uses RenPy 8.3.4, so I guess you'll need at least JoiPlay 8.3.x.
Otherwise, there's always the official Android APK version to try instead.
As of now, the official Android version has no content differences (no reduced image quality or anything).
