Read full description

An idle game where you summon pixel-art spirits, merge them, and grow a little sanctuary. Your spirits keep gathering mana while the app is closed, so the sanctuary is a bit livelier every time you come back. ◆ SUMMON AND MERGE Meet 24 spirits across six elements: Grove, Tide, Gale, Ember, Lumen and Umbra. Put two of the same spirit together and they merge, growing from little to grown to elder. Merging roughly doubles their output and frees up a home, so there's never a bad time to merge. ◆ GROW THEIR HOMES Level up a home for each element (a tree house, a spring, a windmill, a hearth, a light altar and a moon shrine) to house more spirits and boost production. The pixel art of each building changes as it grows. Spirits living in their own element's home produce twice as much. ◆ PROGRESS WHILE AWAY Production continues while the app is closed (up to 8 hours at first, 24 hours with research). Collect it all when you return. ◆ A LIVING WORLD Morning, day, dusk and night follow your real clock, with rain, wind, fog, snow and rainbow days. The time and weather change which elements shine. Shooting stars, wandering visitors, merchants and musicians, festivals that boost production 7x, and the Murk, a boss you tap to purify, all drop by now and then. ◆ BUILT TO LAST - Star Return (prestige): gather starlight and raise all production - Send spirits into the Deep to bring back dew and legend shards - 11 Star Book research upgrades, elemental awakening and 6 x 5 constellations - 6 legendary spirits and rare shiny variants (1%) - Complete the Spiritdex to earn elemental blessings ◆ MUSIC 55 original tracks that change with the scene, plus a jukebox to pick your favorite. You can also layer a 40Hz tone in settings. ◆ CLASSIC The original Idle Spirits block-breaker is still here as Classic in the menu, with all your collection records intact. Every sprite is drawn pixel by pixel with a hand-built rasterizer. Take your time and grow your own sanctuary.

Fly & Math's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.0). On price and device support there is nothing between them.
