Slumber Drift: Idle RPG

Last night's sleep decides today's sky. Slumber Drift is a text-based airship game powered by your real sleep data. Sleep well, fly far. Sleep short, drift close. Every morning is a new departure from the same dock — but never the same voyage. — HOW IT WORKS — Connect Apple Health and set your sleep goal. Each morning, Slumber Drift reads last night's sleep and converts it into two stats: VOYAGE POWER — How far your airship can fly. Determined by how many hours you slept relative to your personal goal. DREAM LUCK — The quality of your journey. Shaped by sleep stage depth (Deep + REM). Apple Watch owners unlock the full ceiling; iPhone-only users reach a solid 0.8. Tap Launch Voyage. Watch the text log scroll: crystal earnings, encounters, events, and zone transitions — all animated in 30 to 60 seconds. — CHOOSE YOUR MOMENT — At every encounter, you face a decision. Retreat — lock in your crystals and end the voyage safely. Press On — risk the encounter for more distance, better drops, and milestone rewards. The further you fly, the harder the encounters. A well-rested crew flies farther. A lucky crew survives longer. Sometimes the right call is to turn back. — BUILD YOUR AIRSHIP — Every voyage drops equipment. Fit your airship with Engine, Hull, and Compass pieces to push your stats higher. Rarity tiers: Common · Rare · Epic · Legendary Higher rarities carry more affixes — and at Epic and Legendary, some of those affixes cut against you. A Legendary Compass might grant enormous crystal gains while quietly taxing your encounter odds. Choose wisely. Reroll affixes with Drift Crystals. Sell what you don't need. Curate a loadout for your playstyle. — DREAM TONICS — Spend Drift Crystals on consumable Dream Tonics. Each tonic lasts a set number of leagues before dissolving. Seven types, from route extenders to crystal multipliers to encounter shields. Mix and match active tonics before each voyage to shape the day. — SLEEP STREAKS — Consecutive nights of good sleep build a streak. Streaks unlock tiered buffs — Gentle Breeze, Steady Wind, Strong Gale, and Eternal Trade Wind — that multiply crystal earnings and improve encounter odds. A streak is worth protecting. — MILESTONES — Reach Lg 50, 100, 150, or 200 and the sky rewards you: bonus crystals and a guaranteed rare equipment drop. These aren't random events — they're earned by flying far enough. — HONEST DESIGN — · No ads. No gacha. No pay-to-win. · One voyage per day.
