After so long I have finally beaten the game. I beat the game right before my game had crashed and lost my saved data, which honestly I don't really mind since I already saw the ending. One hundred percent one of the most difficult games I have ever beaten.
It's difficult in a way that isn't something like Enter the Gungeon, but more like I'm playing chess against a 1500 elo. A pain in the ass but in a good way. Good game!
