Yeah, I kinda agree with you. The sacrfice is there, and I wanted it to be linked to the second incredience (devils attorney), but, as I learned after the jam, I understood that ingredience a bit differently.
The castle was meant to be there a bit more, not just as a blockade that is in the current game.
And finaly, I had an idea for reincarnation, but did not have time to finish it.
