As of v0.5
I love cultivation themes, and I've never seen one on here. So five stars for that. There's a bunch of things done right.
However, I immediately have several complaints. Probably because, as you stated, proof of concept.
For one, stop with the all white screens. I hate it. The menu screen for example. If you could use black or a darker color instead, I and my eyes would thank you. Same is true for other transitions.
For two, the dialogue is literally white text over the picture. Please put a background for the text box. Some games have a slider for the opacity or other such things, but the hide interface button is sufficient.
The default text speed is terrible, but I can easily fix that, so no complaints.
For three, the door of the hut I start in moves when I click on it, which is weird. Temporary assets as you said.
In the scene transition to the cabin with the redhead, she loses her shoes and he fixes her top. However, after returning from gathering medicine, her top is open again. Then when it zooms in it's closed once more.
Skipping through stuff like training results in glitching around the house (Using the rock).
It seems like sometimes when I talk to Mai I can bond with her. But not every time. A dedicated button for that sort of thing would be nice, or at least not having the same dialogue repeatedly. EDIT: There is later a bond button but point kinda stands. Though sometimes reading the dialogue more carefully is nice.
I like the animations, but I kinda also want to skip through the training quickly, since I know cultivation is a bit tedious. Mechanisms to help that are good. It seems you have a couple on further note.
Meditation:
I'm not entirely sure what the point of the two block refill Qi thing is.
I have no idea if I should be buying points to improve stats, or stockpiling Qi to breakthrough because that seems more efficient...
Combat:
I don't get it. There's no enemy health bar. I have no idea what the button to change between fist and sword does, presumably weapon. The stance thing I get but offensive doesn't lower my Qi so I don't know why I wouldn't use it.
Erotic content:
Seems pretty good for the initial. Obviously could use more. I don't know 100% I saw it all, but I got a bunch of "future update" notices, so I"ll stop here.
You have nice icons for the saving and all that- though honestly I'm equally happy with the Ren'Py words I always see.
The models look nice, animations are good.
English is great. No complaints, honestly, it's enjoyable. Its only real flaw is it's the initial release.
I like base building, so the repair of the cabin is pretty pleasing to me. There's implied upgrading living situation, which will be nice.
Things like formations to protect it would be great for later on, but they does inherently limit the types of events possible at that point.
