Whoever survives... I win
Goes absolutely hard, and all three character designs are great.
Gameplay isn't that great, after taking a century to finally land a hit (and killing myself multiple times), seeing it only deal 1 damage on a boss with 10 HP is a via dolorosa. It had to be easier to hit, not damage me and/or be instakill on my side to feel less like a test of patience than a fun game.
Would love to see a narrative game with your characters, though. You nailed the worldbuilding with the few words you've put in and great designs that went with them.
