Welcome to Abyssal Hollow!

Abyssal Hollow is a creepy-cute alchemy idle game where every seed has a fate. Grow mysterious plants in your dark little lab, then harvest them for potion ingredients or bring them into the Abyss as living companions who can attack, shield, heal, and keep you alive.

Venture into cursed depths to battle eerie creatures, collect rare equipment, gather gold, and discover new seeds to grow back home. Just do not ignore your garden for too long. Neglected plants may mutate, wither, or return as vengeful spirits that haunt your future runs!

Experiment with potions, unlock upgrades, expand your laboratory, and build a haunted garden that grows stronger with every descent. Cute things dwell in the dark too.

The Cauldron Always Answers

Drop in whatever you have, stir bravely, and watch the cauldron cough up a potion. Some brews heal, some help, and some should probably be labeled with a tiny skull.

Brew carefully. The right potion can keep you alive, power up your monsters, or crush a boss. The wrong one can make the dungeon much, much happier to see you. The potions you bring on a run can be as just as key to your survival as your character build.

From Seeds to Sidekicks

Battle creatures in the Abyss to collect mysterious seeds, then plant them in your haunted garden to grow adorable monster companions. Raise your little horrors, bring them into dungeon combat, and build a stronger team with every run.

Treat your little horrors with care. Neglect them, and they may turn against you. Let them die, and their restless spirits may haunt your future runs through the Abyss.

Dungeon Combat

We put a fresh little twist on classic idle combat.

Your companion creatures handle the steady fighting on their own, while you jump in with active, cooldown-based skills that shape the battle. Magic skills are your heavy hitters, but they require careful mana management. Melee skills are weaker, but always reliable when your mana runs dry.

You can also support your tiny monsters with buffs, debuff enemies, and use crowd control to keep the Abyss from chewing everyone into decorative confetti.
