Tap to leap from planet to planet, time each jump so you land perfectly, and keep going until the darkness catches you. Every perfect landing builds a streak, every streak lifts the score, and every run reaches a little higher than the one before. The sky is never the same twice. Skirt the pull of a black hole, cross the glare of a dying sun, ride out a comet storm, and find what waits inside the fog. New events unlock as you climb, and each one changes how you play. WHAT YOU'LL FIND - One-tap controls that take a minute to learn and a long time to master - Handmade worlds and events, each with its own hazards and rhythm - Perfect-landing streaks that reward timing over reflexes - Shields and guides to bank for the run that matters - A hangar of skins to collect and ride - Full haptic feedback EMBER is free to play. Optional shard packs and a one-time remove-ads purchase are available.
Black Hole Gravity
Read full descriptionHide full description
Black Hole Gravity is a quiet arcade about one instrument — light — and the one thing it can do here: bend around a black hole. You are the last keeper of the horizon. Drag to bend the beam: far from the hole it barely curves; close to the photon sphere it wraps around once, twice, three times before it leaves. Tap to fire a pulse along that path. Where it lands, matter moves. THREE ACTS I · THE WATCH — Worlds are sliding toward the horizon. Push them clear with light and hold the line for as long as you can. Every world you lose feeds the hole and makes it grow. II · THE NIGHT — The stars are out. Nothing to guard, nowhere to hurry. Bend the beam, watch it wind, and score by how far it turns. III · THE SOWING — The universe is cold. Push the last worlds into the singularity, shatter them into falling fragments, and grow the hole until it collapses into a new Big Bang. DEEP TIME One long run through five scales — from asteroids to whole galaxies — each around a real black hole: Cygnus X-1, Gaia BH3, Sagittarius A*, M87*, TON 618. Your enemy is Hawking evaporation. Five eras of the far future set the difficulty, and every singularity you reach births a daughter universe with slightly different laws. HONEST PHYSICS • The lensed sky and the Einstein ring are computed from the real mapping, not painted. • Winding the beam with the hole's spin draws on its rotation — superradiance (Zel'dovich 1971; Press & Teukolsky 1972). Each amplified shot slows the hole; accretion spins it back up. • Mass, Schwarzschild radius, Hawking temperature and evaporation time are shown live, computed from the hole you are playing. • Bodies that leave the screen are never teleported back: an escaping one is gone, a bound one returns on its own orbit — the edge marker tells you when. • Nothing changes under your finger. While you aim, the world waits. CONTROLS Adaptive aiming: the gear ratio next to the ship shows how fine your aim is — the closer to the capture boundary, the finer the control, so a three-winding shot is as steady as a straight one. A hardcore scheme with a log slider is there for those who want it. Two beacons, one under each thumb. A procedural soundtrack, four tracks, made from the same math. Sound designed for headphones: low pulses and singing bowls, nothing arcade. No ads. No tracking. No account. Works offline.

Verdict
The clearest difference is in-app purchases: Black Hole Gravity at none against EMBER's 3. Black Hole Gravity also leads on ads (none vs shown). EMBER's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
