He implemented a patreon wish which took a LOT of time. The clothing system in this game means that for every scene and every body position (a good example for body position is Lisa and Alice on the bed or Lisa and Olivia at the pool) there has to be made several renders. Some rooms even have different daytimes, so the lights are different for the renders as well. That's a HUGE amount of images to be rendered. After that the overlapping elements have to be cut out to save disk space (we don't want another 20GB game, do we?). Maybe the render process is a bit optimized, if not the whole image has to be rendered just to replace a skirt with a towel, I don't know if his software can do that.
After that there comes the logic (which probably took most time). For each scene depending on various variables it needs to decide which layers have to be combined into the final image, for example depending on the time of day or what clothing was chosen in the menu. This would be a lot of work in a real programming language, but doing that in a simple script engine like Ren'Py? That's hell on Earth. Implementing this system took a lot of time.
An then there all the random scenes. You can catch Lisa while changing, I think there are 6 poses for that + reactions. The single clothing components are: panties, bath towel, headwrap, school skirt, school blouse, rose skirt top, rose skirt bottom, rose skirt top half up, pink top, blue skirt, red bikini bottom, red bikini top, white dress (I missed probably a few).
That's quite a few pics to render.
From a game like this (free roam, different day times, different character positions, different clothing) one you can't expect the same amount of story progress as you do from visual novels.
Yes, he might be over his head with this project (at least he now got some people who help him test and translate), all we can say is that he is still working on it. The solution for you/us as players is the same as always: If you don't like it, don't pay. Problem solved.
