I have two reason for writing this first impression: first is that Jusant is pretty fun game, and second is to tell of the trouble I had running it on Linux.
Let’s get that second point out of the way first: I’ve been running Linux (Debian, in case you were wondering) since late last year on my home computer, after getting fed up with Windows and its file system quirks. Since then, I have had the unusual opportunity to find out exactly how many games will “just work” on Linux, aided greatly by Valve’s work on Proton to make their Steam Deck as compatible as possible. The answer? There are more games that just work with Linux than there are games which just work with my monitor (you wouldn’t think supporting ultrawide 32:9 aspect ratios would be such a problem these days, but at this point I will react to “fixed vertical FOV” the same way a vampire does to garlic). Jusant was the first game which gave me real trouble, which was even more annoying given that everyone online talked about how it worked perfectly. So: for those who stumble across this post in their desperate search to figure out why Jusant is stuck on the splash screen and never does anything but give weird DirectX stack overflow errors in the proton log no matter which branch you try, the answer was to disable DLSS by deleting the nvngx_dlss.dll files from the install folder (thanks, person on a subreddit for a completely different game).
Okay, with out of the way, we can actually talk about the game. Jusant is a climbing simulator where you control an androgynous figure who lives in a desert that has a strangely large quantity of references to tides, water, and boats. You begin your ascent of a tower of seemingly infinite height, slowly learning about the previous inhabitants and the fate of the strange world you find yourself in.
And that’s about it, really. Honestly, this game could be twenty minutes long or twenty hours long and I’d be okay either way – the climbing mechanic is satisfying enough that I can imagine having an enjoyable time no matter the length (though my understanding is that it is about 4-8 hours long). Jusant knows what it is and presents just a strangely calming walking/climbing simulator with style. My complaints are limited, though I believe slightly more challenging climbing and more alternate paths would improve the experience (I’ve only played an hour, so some of my wishes may be fulfilled). Jusant is just a pleasant Tier One game.
ETA: Having now returned (and completed) Jusant, I can say that it does (barely) keep its Tier One rating. The climbing evolves a little, but the new mechanics are explored only briefly and without either the threat of failure (it’s literally impossible to) or much more diverse/difficult climbing sections, the experience waned in its second half. I completed it in roughly 4.5 hours, though I apparently missed a few letters on the way up. In all, it suffers from the same problems as many walking simulators (a severe lack of mechanics or challenge and not enough substance to warrant a replay), but the climbing was at least briefly enjoyable enough to sustain it.
