These are good suggestions. Some commentary and clarifications:
The wardrobe is very old code that will need to be rewritten at some point. Sadly the clothing system is such huge mess that the sheer amount of time to refactor it lowers its priority. As long as it’s “functional” I thin kit’s better to focus on other things.
Not sure about the tears and ghosts. I haven’t touched those at all. Perhaps there’s a certain body part size in particular that is affected?
The controls can be mapped to whatever you want them to be. I use “X” as one of the default cancel keys because it’s the RPG maker standard and is used in thousands of eroge. I agree it doesn’t really make sense, but too many people are used to it.
