I love this game so much, but after spending probably a month on and off burning Kalameet's moveset into my very soul... I think I'm taking a break from more challenge runs lol.
No I just do it for myself... I take a screenshot at the end for posterity but that's about it. The game is really beautifully designed in that everything that happens is predictable if you know what to look for. So it's just a matter of doing it enough times to memorize all the tells, and how to react to them. I find that aspect of the game extremely satisfying, so I keep coming back to it.
