A colour-sorting puzzle set in the ocean, from warm shallows down to the darkest trench. The glass vessels glow like deep-sea creatures, and each pour arcs from one to the next. These notes follow the shape of a dive plan.
Buddy check
Tap a vessel, then tap where it should go. The whole upper band of one colour moves across, as much as fits, but only onto the same colour or into an empty glass. Each column holds four bands. Every level has been checked by a solver, so a clean solution always exists.
Descent
The Depth map holds 60 levels in six zones of ten: Sunlit Shallows, Kelp Shelf, Twilight Drop, Midnight Water, Abyssal Plain and Hadal Trench. Colours grow from three to twelve on the way down, and the zones open in order.
Bottom time
Each level has a par, the length of the solver's own route. Match it for three stars. Undo, a one-off spare glass, a hint that follows the solver's plan and a restart sit in four round buttons below.
Ascent
Dive mode chains puzzles on a single breath of air: par plus six pours for each one, a colour harder every time, and one spare glass for the whole dive. The last 20 dives are kept with their points.
Safety stop
Twelve badges, from First Pour to Sea Floor, mark the milestones. The Logbook counts pours, points, undos, spare glasses and three-star clears, with stars for every zone.
Surfacing
A glowing orb at the foot of the home screen opens a radial menu of five petals. Shafts of light sway, orbs drift and bubbles rise behind the menus; this animated background can be switched off in Settings, next to haptics and a progress reset. The game plays offline, with no account and no ads.
