Fight against Paimon, the Demon Lord of Spirits and representing the Deadly Sin of Pride. You play as the Crusader Class with the Crossbow weapon. (There are 4 classes and 9 weapons.) WASD or arrow keys to move, hold e or LMB to shoot. (This is only one boss fight in my biggest project yet, a full dungeon crawler rogue-like game.)
I made all of the pixel art in this project, do not use it without my permission. Yes, the boss is possible, I beat it, so no saying it's impossible, and if you say "it's too hard," that's the point, it's a boss, it's meant to be hard.
