The player controls a lone wanderer as they climb a desolate tower, filled with the artifacts of civilizations long past.

Jusant tasks the player with climbing to the top of a tower, which is split into different biomes, each with unique traversal mechanics and challenges.

Several generations prior to the start of the game, the Tower was surrounded by ocean, and was settled by a large population of people that lived throughout the vertical structure, adapting by developing relatively advanced climbing gear and placing ziplines and grappling points throughout.

[16] Destructoid liked Jusant's peaceful atmosphere, highlighting in particular the sound design, "Its use of silence makes it the perfect game to throw on when you’re listening to a podcast, or if you want to unwind for half an hour before bed".

[17] Game Informer felt that not enough time was spent polishing other forms of traversal, "walking can be troublesome as the character has a habit of getting stuck on even the most negligible geometry, such as small pieces of rubble, resulting in awkward jumping and spinning to break loose".

[18] Rock Paper Shotgun praised the open-ended nature of the game's narrative, saying, "Like an actual archaeologist, you must sometimes make informed guesses, fill in some gaps with gut instinct, and tread carefully".

[19] In February 2024, ''Le Syndicat des Travailleurs et Travailleuses du Jeu Vidéo'' claimed Jusant apparently failed to meet commercial expectations, with the production team being disbanded.
