It shows you put a lot of effort into this. So, I don't want to dissuade you from continuing.
However, the platforming is rather annoying. The jumps seem too floaty.
The AI gets stuck too easily, but get alerted in such a manner that it is almost impossible to avoid damage when they drop down.
Plus the first enemy (I'm assuming some sort of ghoul/zombie) doesn't have any details, but the blue spirits and eye monsters look just as detailed as the main characters.
You do have a good story, but the big demon at the end seemed like it was Scarlet's boss, until you read "no girlfriend" at the end.
I do like the fact that you put the effort into making multiple endings.
Overall, it can be a lot better, but for what it is it is okay.
I hope to see your future works.
