Critadel help?

Been playing Critadel on Switch recently, since I want to unlock the Curly Brace alt costume for Nox. But the game is too obscure, there's virtually no info online of it, much less what I'm looking for. In-game, the alt used to say what you needed, but that changed to "???" at some point. I figured this might be the best place to ask, since the "Cameos & References" lists it.

Please, somebody help me.

Alright, I don't know much about Critadel but from what I've seen you apparently have to find stuff to get skins for Nox, you might also have to beat the game as well?

Please take my words lightly because of my lack of knowledge about this game.
