Played the (gigantic) demo for this, it's a PS1 throwback platformer with crunchy low-fi textures and lovely pastel lighting reminiscent of Spyro.

The movement is thankfully much more modern: it's a sort of greatest hits mashup of Mario Odyssey's basic jumps, Prince of Persia's wallrunning and pole spinning, Ratchet's rail-grinding, and Tomb Raider Legend's physics-y grappling hook. Every move is totally analog, with no canned animations or snap-to ledges, and the level designers wring every last ounce out of the repertoire with some of the toughest, most inventive 3d platforming levels I've ever seen.

One level in particular is an extended, hours-long homage to the central temple climb in Shadow of the Colossus, and it's maybe the best 3d platformer level I've ever played. It's a single massive structure that you climb up and around and outside and within, discovering hidden paths and outlandish new moves in search of the summit. The [REDACTED] at the top has immediately become one of my favorite places in games.

The rest of the levels aren't quite so good, and the difficulty is fairly steep throughout, but if you're willing to fall down a zillion pits this demo's an absolute must-play.
