I like the game so far, it is cliche in a fun way which I enjoy.
Combat is enjoyable, maybe you should be a bit more generous with the hit boxes but so far it's good.
From the front facing perspective you're character's clothes look very blocky and somewhat the same from the back as well, sides look fine though.
You might want to not put ceilings on the parts where you transition from room to room as it just looks like a wall.
In terms of the inn bath scene I'd say you should add a animation of the tail swaying a bit and maybe make her look less stiff, her arm being to her side staying still makes it look as if she is really tense.
The scene following suit is better but the penis does look disconnected from the rest of you're body, overall that scene is good but some touches here and there can make it look much better.
Maybe you could make a animation where she rests her leg on the bed after finishing, more of a suggestion though.
Next scene looks good as well, no noticeable things to say about here.
Next scene could be better the tail is again, really stiff and from the perspective given it looks like you're character doesn't have two legs.
The breasts on the girl start swaying before you push into her which looks a bit weird, and you're character's arm looks abnormally long.
There are a few grammar issues in these scenes but it wasn't too noticeable.
Xray button continues dialogue which is annoying.
You should have item stats shown in the shop before you buy, also it doesn't make too much sense for the most expensive sword in there to have less durability then the one before it.
I'd recommend refilling the players health after the stay at the inn, buying potions to max health after didn't make too much sense.
Overall the game so far is great for being from one person, I have a lot of respect for you as making this must have been hard.
I don't think I missed any content but I definitely could have.
