Quick update: The Healer’s Assistant fix was super simple. The secret boss has me a bit stumped. Might take me another day or two to get the fix out. The code absolutely looks correct, so if you’re getting sent to the docks on a win, I likely have to re-test the entire current Steam release up to that point myself.
I did think of a rather large secret for you. I would HIGHLY RECOMMEND SAVING before even beginning to attempt this.
Somewhere in the Academy are three hidden engravings. They must be pressed in the correct order, and only once. Finding them and pressing each one, in the correct order, only once, will allow you to access a passageway that looks impossible to access (it is also in the school).
Doing so will allow you to access…
Developer tools!
Be VERY careful if you play with those. They can be fun to mess around with, but it will be INCREDIBLY easy to break that save file. I would save in one or two dedicated slots just for that.
