Sundrisse: A Star in the Well

Field notes

Party members move together in real time: the player controls one child and switches to another with a single button, while the others follow. Each has a distinct traversal tool—Lumi’s grappling hook, Tenzo’s chained spring jumps, and Rui’s heat-riding umbrella—so routes depend on who leads. The page says the demo covers two layers and one boss; the complete version is described as twelve layers with nine bosses.
