It’s quite different from Jusant. I found Jusant to be to arcade racers what Cairn is to simulation racers. Jusant was like a puzzle game with a climbing aesthetic, whereas I found Cairn to be truly about the climbing.
I played the demo for Cairn and genuinely can’t remember the last time I had a sense of accomplishment in a game that compared to teaching the top of the demo climb… And then the reveal of how much farther you’d go in the full game. It was very exciting for me. A very novel, interesting experience for me.
As for Witchbrook, I love Stardew Valley and magical fantasy, so that is looking like a no brainer.
