Read full description

Dodge readable bullet patterns, graze for Phase Pulse, and chase clean weekly scores against the Pattern Engine. Description: I.S.U.D. Zero is a portrait bullet-hell boss rush built around clean reads, a tiny fair hitbox, and fast retry mastery. Enter the simulation chamber, learn each boss pattern, graze close calls to charge Phase Pulse, and chase cleaner clears across The Instructor, Mirror Cadet, Twin Array, and The Cartographer. Every run is short, sharp, and score-driven. Bosses move, mutate, and escalate through multiple phases. The ship only takes damage at the red core, so the chaos stays readable even when the screen blooms with bullets. Features: - Precision drag controls for portrait play - Fair red-core hitbox with optional callout - Graze scoring and Phase Pulse screen clears - Four multi-phase bosses with distinct patterns and visual escalation - Five additional boss slots marked Coming Soon - Difficulty options, persistent best scores, and ranks - Game Center weekly and all-time high score leaderboards - Neon arcade presentation with original audio hooks

Set sail in Leave Her Johnny, a cozy pirate adventure with warm, hand-drawn charm and a whole ocean to plunder. Captain your ship across 8 themed seas — sunny shallows, frozen straits, and the haunted deep. Hunt navy warships and merchant convoys, raid their cargo, and pour the spoils into a deep upgrade tree: bigger hulls, faster sails, heavier cannons, and a hardened crew. Cripple an enemy ship and storm her deck — lead your marines across the enemy ship, fight through her defenders, and fell the Captain to double your prize. Drop anchor to send a shore party ashore: explore islands on foot, dig up buried treasure, and battle the creatures guarding the sands. Face bespoke bosses — the Coral Colossus, the Hoarfrost Leviathan, and Davy Jones himself — then see how long you last in endless Open Seas mode as the fleets and storms keep coming. FEATURES • 8 hand-crafted seas + endless Open Seas mode • A deep ship upgrade tree with real tactical tradeoffs • Boarding parties — storm enemy decks in close combat • Shore parties — explore islands and dig for treasure • Bespoke boss fights with unique attack patterns • A songbook of sea shanties and a living, procedural score • Achievements, records, and a captain’s logbook to chase • Plays great offline — no account, no sign-up, just sail Weigh anchor, Captain. The horizon’s waiting.
