I'm surprised there isn't already a thread for this.

Most simply described as "Suda Souls," but so much more than that. Climb the increasingly difficult Tower of Barbs. It feels like Souls in a lot of ways, but oh my god. Grasshopper through and through. I've just reached the second big boss and have so far been having a blast.

Just try it out.
