Achievements and trophies

Checked 14 October 2026. 32 Steam achievements, including campaign clears, Gold rooms, Antipode, sky, underworld and endgame milestones. Later names below contain spoilers.

What I checked

Source check, 14 October 2026: the public Steam achievement page supplies all display names and its available descriptions; the percentage API supplies internal IDs. Percentages below are the API snapshot, not personal completion or a PS5 trophy list.

World clears and gold

The Steam achievement page identifies the first four as initial campaign clears. The six Gold achievements unlock when the corresponding room is opened. B in the display names means Beamcasters; P remains in the older internal IDs.

These rates are a population snapshot, not a difficulty ranking or your percentage of completed puzzles.

Towers and the end

The Antipode achievement descriptions require activating the pair's teleporter. Steam gives no visible condition text for several later achievements; the table leaves those conditions unknown rather than deriving them from an ID.

The public HTML displays 0.1% for several rare achievements while the API rounds them to 0.0%. A rounded zero does not mean an achievement is unobtainable. This table keeps the API values and date rather than blending the two presentations.

Missing demo achievements and PS5 trophies

The 12 October developer patch awards missing achievements when a demo player's save is loaded. Update the Steam version and load the existing campaign before considering destructive troubleshooting.

The Steam list does not establish the PS5 trophy count, Platinum requirements or missable trophies. No first-party trophy list was verified here, so the page does not copy a competitor's claimed count or promise that nothing is missable.
