Nyacronomicon!

Nyacronomicon! Nyacronomicon! puts you in a cat-eared apprentice witch’s shoes, pulled into a cursed grimoire world. Battle greed-born monsters, lose memories on defeat, and uncover lore to find your way home.

Nyacronomicon!

In Nyacronomicon!, you step into the role of a cat-eared witch-in-training whose life is shattered by a strange necromancer’s book. Trapped in an eerie world, you’ll run into greedy souls and unsettling monsters. The big question is simple: can you make it home again while losing your memories along the way?

Every time monsters defeat you, you’ll trigger dramatic defeat scenes that are both intense and personal. But if you lose too many times, the book may keep you—cursing your memories and locking you deeper into its pages. Proceed carefully; your fights aren’t something you can brute-force.

Story of Nyacronomicon!

Shiro is an apprentice witch with cat ears, determined to become a true master one day. One afternoon, while tidying the forbidden archives under her strict mentor Cronia, she stumbles across a glowing grimoire: the Necronomicon.

The ancient tome drags her into its sealed realm—a labyrinth where floors shift over time and monsters take shape from the memories of greedy souls. In this world, defeat isn’t just losing a battle: you lose everything, return to the beginning, and start again. The one comfort is the relics you collect, which let your progress carry forward gradually through endless loops.

Can Shiro learn the dungeon’s secrets, resist her own darker urges, and find a path back home? Or will she become just another memory trapped inside the book’s cursed pages forever?

Player Comments of Nyacronomicon!

• “A 3.5 star game, realistically.” It can feel very easy—maybe I got lucky with my build. I even reached the good ending on my first run (though I admit I save-scummed after running into bosses without paying attention). Midway through, I was healing off most enemies, which snowballs you quickly. Replay value is also limited: a “good build” mostly means taking a scaling passive early and stacking stats, since specialization only really matters on the early floors. Also, the choice to include defeat scenes is confusing—you can’t see most of them without actively seeking out losses to weak enemies (or walking around on autopilot). The gallery unlock pacing feels off too, and overall the game’s not bad, it just doesn’t stick long-term, and the H-scenes feel disconnected.



• “Honestly, not a hard game.” After a bit of figuring out what works, it gets easier. Keeping an eye on stats and going for flat stats early helps you reach the late game. About an hour in, you get scaling gear and then it’s basically game over. I even forgot about collecting CGs—turns out the game’s clear screen triggers a gallery unlock.
• “Pretty nice game.” It’s like a roguelite dungeon crawler (not sure if there’s a better label). Enemies don’t move and only fight back when you choose to engage them. You can use 1 skill and 1 item on them safely, and battles play out automatically. Gold, potions, and chests are scattered across maps, and there’s a simple stat-point system that’s easy to miss. At first it’s cool, but it can get repetitive once you realize it’s mainly about health management and the floors aren’t procedurally generated (aside from enemy behavior, kind of). Eventually you learn each run’s routine and just hope you roll strong artifacts to steamroll later. One big annoyance: you can obtain and even upgrade duplicate passive skills that boost your stats (like Passive HP, Passive Attack 2, etc.), but they don’t stack—so you have to track which passives you already have or you risk wasting rare chests or gold. It also feels inconsistent since duplicate active skills/spells (like Judge Bolt, Wall, etc.) can’t be obtained. Another issue: you can’t check artifact effects unless you select them in your inventory, meaning early runs involve blind guessing. Visually, the art is good and there are plenty of CGs, but I don’t like that you need the true ending to unlock the full gallery—other endings won’t grant access, leaving the full gallery locked. Still, overall it’s one of the better games and worth checking out if it interests you.
