About this game
Forge your path!
The world was broken by hubris. Alchemists once tried to create perfect life, and their failures left scars across every nation. The result where the Humunculi — beings born from sin, each embodying pride, wrath, greed, and more.
You play as Fumiko, a homunculus unlike the others. She is a blank slate, born without sin, searching for what it means to be human. Along her journey, she’s joined by companions with their own voices, histories, and reasons to travel east. Together you’ll cross deserts, jungles, ruined kingdoms, and holy empires — each with its own sayings, traditions, and secrets.
Gameplay
At its core, The Hollow Alchemist is a roguelike deckbuilder. Combat is fast but thoughtful, built around elemental combos, buffs, debuffs, and companions. Every run offers new choices, new cards, and new fragments of story to uncover.
Proper Alchemy
Water buff extinguish Burns - Wind buffs increases your Burn - Earth buffs absorbs water etc. etc.
you get the idea... all your buffs interact with each other as it is proper alchemy at works during the fights!!!
Evolve
The road isn’t just about battles. On the nodemap eastward you’ll stumble into quiet villages, war-torn ruins, and the occasional eccentric homunculus who insists on testing you with puzzles that are… let’s say, creatively designed.
Each Sin you confront leaves a mark. Marks grant you power, but they also change you. The more you use them, the more their voices creep into your own. The challenge is not only to survive — it is to decide what kind of being you will become.
Beyond the standard cards, you can also create your own. Unleash your creativity and combine the four elements however you like!
We can’t wait to see what wonders you’ll bring to life—awaken the alchemist within!
Features
Build decks from Fire, Water, Earth, Wind — or just pummel your enemies if that’s more your style.
Dice-based mana makes every turn a mix of strategy and luck.
Summon companions who fight (and occasionally sass) alongside you.
Explore thirteen nations, each with its own history, culture, and flavor of trouble.
Face your family of the Seven Sins.
Roguelike runs with branching stories and plenty of reasons to come back.
About This Game
The Hollow Alchemist is inspired by the roguelikes we all love but leans, at least a bit more into narrative. Cards aren’t just numbers — they’re fragments of alchemy, each tied to an element and a reaction. Buffs and debuffs stack in different ways, from steady burns to sudden collapses.
The story matters as much as the fights. This isn’t a faceless roguelike loop — it’s a journey about identity, sin, and humanity, with companions who bring their own perspective to the world. Some moments are light and colorful, others dark and reflective.
Yes, it’s a game about building decks. But more than that, it’s a game about building a future.
I AM SCARED TO ASK BUT... if you like what you see...would you leave a wishlist?

Hey everyone!Merry Christmas, before i go into the holliday i thought I update you guys on the progress ;P I made good progress in the 2nd and 3rd country and I suspect I can finish that up in Janurary. Also I layed out already the 4th and 5th Countrys Nodemap and my story beats there! I streamlined a bit my Enemy cards and created many attacks and such and created new enemies along the way. by new years my character modeler also creates new 2 new enemy models. As you can see its going smoothly, and considering the 6th country (Cindrel) is my goal for, when it is done, starting early access I am quite excited that it seems like I can start Early access in the First Half of 2026!!! With that, Enjoy your holidaysRead full article on Community Announcements (Gin)
