The Providence Trials are awesome! They're probably my favorite part of this version of the game. But, user-made trials are damn near impossible to implement currently. I tried to use UndertaleModTool to open up the game and to see if I could work from there, but since the game is compiled using YoYo Compiler, all the scripts are stored within the executable, and they're also all written into the executable in assembly, so even if I could access them, they'd be incredibly difficult to work with. That just leaves the existing Providence Trials to fiddle around with, and unfortunately, all of the related files are made with in-house programs and saved as their own extensions, so they just come up as gibberish in text editors.
So, my request is this: would you be able to release the program used to make Providence Trials so that players could make their own custom trials? I understand if you can't, but I feel like it's worth asking, if nothing else.
