Hold
Press anywhere and the orb inflates, then climbs. It builds speed rather than jumping.
Fathomling — Android
A one-finger dive into a reef that lights itself. Scoop the motes, weave past the urchins, and see how far your nerve takes you before the water gets busy.
Free to play. One optional purchase removes the ads.
0 m — the surface
Most one-touch games make you tap. This one makes you breathe. Your finger controls buoyancy, and buoyancy has weight and lag, so the orb keeps travelling after you let go.
Press anywhere and the orb inflates, then climbs. It builds speed rather than jumping.
Let go and the water takes over. Sinking is not failure, it is how you line up the next climb.
Slide your thumb across to steer. The orb chases your finger, so aiming is fast and forgiving.
30 m — the reef thickens
Captured on a phone, not mocked up. The glow, the urchins and the particle bursts are all drawn by the game at sixty frames a second.
60 m — the dark part
This is not a tap-to-flap clone wearing a diving mask. Buoyancy fights gravity with damping in between, so the orb glides, overshoots and settles. Learning to read that lag is the skill the whole game is built on, and it is why a run you nearly lost can still be saved.
There are no banners and no interstitials. The only advert is one you choose to watch, to revive once after you have already died.
A grown-up question stands in front of every purchase. Kids Mode tightens it further and hands out a free revive when no advert is loaded.
Every chime and thud is synthesised as it plays. Nothing is streamed and nothing is stored, which is part of why the download is so small.
There is no account and no leaderboard server. Your best depth is written to your phone and never leaves it.
Deeper still
Fathomling asks for no account and collects no name, email or phone number. Your progress and settings are stored on your device.
Purchases go through Google Play, so we never see a card number. The one optional advert is served by Google AdMob, which does receive device identifiers in order to deliver it. Those requests are tagged as child-directed, under the age of consent, rated G, and non-personalised.
Read the full privacy policy or get in touch if something here is unclear.
Fathomling arrives on Google Play shortly. This page will carry the link the day it does.
