Undersun is live: ten floors down, and the sun is singing back

Nine hundred years ago the Choir of Dawn sang the sun down into the earth and sealed her beneath ten vaults. Each vault holds one verse of the hymn and one Chorister to guard it. Now she is singing back, and you are one of the Unsung.

Undersun: Roguelike Pixel is out now on Google Play. It is a portrait, one-thumb pixel-art action roguelike built for short runs and long descents.

What is in the first release

Ten biomes, ten floors per run. Sunken Crypt, Mycelial Hollow, Drowned Cistern, Ember Forge, Frostbone Caverns, Thornwild Ruins, Clockwork Ossuary, Sandsunk Necropolis, Glass Abyss and the Heart of Dusk. Each floor builds 16-20 procedural rooms and ends in a Chorister boss.
Five heroes. Aldric the Oathknight (sword and shield, Shield Bash), Wren the Lamplighter (crossbow, Flare Volley), Morrow the Gravesinger (homing soul orbs, Requiem wisps), Brakka the Bellbreaker (bell-hammer, Toll shockwave) and Sable the Duskblade (twin daggers, Shadowstep).
104 items. 64 bases and 40 legendaries across five rarities, rolled with 24 affixes. Lifesteal, thorns, skill haste and gold find all change how a run plays.
Forty creatures. Thirty regular enemies with distinct AI, plus ten multi-phase Chorister bosses with their own arenas, hazards and break gauges.
Rooms that are not all fights. Old Tallow's shop, sunstones with run-long boons, pilgrims with lore and gifts, campfires, and risky events: gambler's dice, sun shards, a weeping statue, a chained chest.
A story that continues between runs. Twelve main chapters, twelve side quests with permanent bonuses, a codex that fills as you defeat creatures, and narrated prologue, floor and ending cinematics.

One thumb, on purpose

The game is designed to be played with a single thumb in portrait. The joystick floats under your finger (or stays fixed if you prefer), the attack, dodge and skill buttons sit within reach, and a contextual TALK / TRADE / TOUCH button appears when a room has something to interact with. There is auto-aim, haptics, a left-handed layout and a one-time tutorial.

Art, sound and honesty

The pixel art, tiles, UI, enemies and items come from custom generators curated in Aseprite; the eleven music tracks and 34 sound effects were synthesized offline. AI image generation was used for the app icon and the cinematic key art, and that is disclosed on the store page. Every screenshot and trailer frame is captured from the real Unity build.

Fair monetization

Undersun is free to play. Ads appear between floors and can be removed with a one-time purchase; rewarded videos for extra gold or a second chance are always optional. No loot boxes, no pay-to-win, no energy timers. It also plays offline with no account.

What comes next

The first update will focus on the things players ask for most: more build variety at high floors, clearer boss telegraphs, and quality-of-life fixes for inventory comparison. If something feels unfair, tell me exactly which floor and which enemy — that is the most useful bug report I can get.
