Gravimancer
Read full descriptionHide full description
YOU DON'T MOVE. GRAVITY MOVES EVERYTHING. Gravimancer is a magical physics puzzle-action game built around Apple Watch—not squeezed onto it. Tilt your wrist to rotate gravity for the entire world. Your glowing orb, pursuing enemies, loose rocks, crates, lava, and water all roll together. YOUR WRIST IS THE CONTROLLER • Tilt to rotate gravity through the arena • Turn the Digital Crown to choose one of five force strengths • Tap to shield your orb and pulse nearby matter away • Feel the haptic engine respond to simulated force and impacts • Mute themed audio at any time without losing haptic feedback SOLVE IT YOUR WAY Every moving object can become part of the answer. Crush a pursuer with a crate. Cool lava with water to make a rock. Let an enemy hold a pressure plate. There is no single route to memorize—only a physical world to understand. FIVE WORLDS. ONE BROKEN SKY. Begin in the Crystal Cradle and unlock each increasingly dangerous realm in sequence: Ember Engine, Sky Ruins, Frostfall, and the Void Heart. Full-screen illustrated story chapters connect the journey as gravity grows less stable. FACE NULL In the final world, Null pulls gravity toward itself. Turn the rolling world against the boss, break three ordered seals, and restore the sky. Finish the story to unlock unrestricted replay of every realm and continue chasing stars. A complete Apple Watch adventure. No ads, subscriptions, accounts, or in-app purchases.

Welcome to ArcadeOS — a whole arcade in your pocket, and now on your wrist. 68 hand-picked original games, each one its own cartridge: full 3D open worlds, kart racers, ninja action, gothic pinball, paper-craft RPGs, sky shooters, momentum platformers, run-and-gun, belt brawlers, puzzle boxes and rhythm. Every game is an original creation in the spirit of the golden age of consoles — drawn in code, scored with real chip audio, and built to be picked up in seconds. HALLOW EDITION Worlds, not cartridges. LOOSE KEYS: HALLOW HOLLOW is a full 3D open city under an orange moon: take any car, hearse, helicopter, plane or boat, outrun a three-star heat system, fly a fast jet off a military airfield, land an airliner at the international airport, and work a phone full of jobs — in a city full of witches, skeletons, horsemen and the odd creature from an 1818 novel. At its heart is HOLLOWMERE, a haunted theme park with a graveyard coaster you can actually ride, a drop tower, and a lagoon parade with fireworks on the hour. MODS ship with it: god mode, every weapon, flight, moon gravity. IRONBARK is a heavyweight momentum platformer: an armored-bark brawler and a glider partner tag-teaming through an industrial jungle of barrel-cannon chains, mine-cart runs and hidden bonus rooms, drawn in fine-pixel art. GLIMMERGLASS KEEP rounds it out — a free-roam 3D collect-a-thon built over 25 nights of iteration. All three have original soundtracks synthesized live inside the app. CHERRY EDITION 23 games rated five stars by our testers before they shipped — look for the cherry on the cartridge. Highlights: Reefjack's lantern-tide run-and-gun, Thornhollow's gorge platforming, Quiet Falls' suburban-oddball RPG, Emberline's three-winter family saga, Cascabel's commedia brawler, Ironvane's vertical shooter, and Crestline GP's speedboat regatta. APPLE WATCH ArcadeOS ships with an Apple Watch app. Six games are built for the wrist and the Digital Crown: Redline Ridge (crown hops lanes, hold to burn), Sunstrip (crown steers, tap to shift), Ironvane (crown flies, hold to charge, tap to call your wingman), Truck Simulator (roll the crown and the truck drives itself — steer, hold to brake, deliver the cargo), Haywire (a horse loose in a farmyard full of physics: buck, jump, cause chaos) and Cairnglass (a crown-controlled falling-sigil puzzler). Runs on its own — no iPhone needed nearby. FEATURES 68 games — every one with its own hand-crafted cartridge art Home screen: your games as icons, with folders you make yourself Gold-star collection: beat a game, earn its golden seal. Collect them all Authentic chip sound in every game, and full synthesized soundtracks in the 3D worlds Instant resume — every game remembers exactly where you left off No accounts. No ads.
