Fathom

Fathom is an idle deep-sea salvage game. Your ship dives, cuts scrap from wrecks along a trench wall, surfaces and unloads, all on its own. Refine the scrap into alloys, upgrade the hull, air and hold, and go deeper. Each border is guarded by a Leviathan you must beat to pass.

Early development build: it updates automatically as the game grows. Progress saves in your browser. Feedback in the comments is very welcome, and the build number at the bottom of Options helps with bug reports.

No ads, ever.

Fathom shares anonymous play stats (which goals players reach, and errors) to help fix what trips people up: a random id, no names or IP addresses. Turn it off in Options. Your run also backs up under a restore code (Options → Cloud save), so you can carry on on another device.
