Mod support works pretty well (although internally for now), but in order to make mods, I need to teach you how to do that for Orchid Rain. I took some days to write you a very thorough guide. You can see it right now and get a sense on what sort of things you can do with the new moddable release at the end of the month.
I've never done something like this before, and I have no idea how many people go out of their way to enable mod support for their games. I did this as I learned, so this system is not perfect, but still there are a LOT of things you can do with this.
Take a look at the modding user guide here.
