Dream Sewers
Every night, Sookuma descends into a dungeon that rearranges itself beneath the dream. Every step is a turn, and the noise of battle draws something out of the dark.
The moment you steal the Dream Crystal from the very bottom, the whole dungeon wakes up. From then on, you have to make it back alive to the Silver Stair on the first floor.

STORY
Every step is a turn. You can see only as far as your torchlight reaches, and noise travels through the corridors.
Somewhere on the deepest floor, the Dream Crystal lies sleeping. Take it, and the rules change as the whole dungeon wakes up.
Every floor you fought your way down becomes your escape route. Choose where to spend the supplies you have left, and climb back up before the dream closes. There are three endings.
Full game overview
Branch dungeons split off below the main dungeon. Each branch has its own terrain and smell, and its master waits at the deepest point.
The details and numbers below come from the full-game description on the Steam store. The Steam page does not say how much of it the demo covers, so download the demo and see for yourself.

Nineteen gods wait at their altars, each with its own voice, temperament and powers. Before you serve one, you can hear the god describe its covenant in its own words.
Hover over a god you can meet in the demo (or tap it on a phone) to preview the covenant card that appears at its altar.

Full game overview
Potions, scrolls, wands and relics won't tell you their names. Their looks and identities are reshuffled at the start of every dream, so you learn them by using, reading and surviving.
Monster packs and elites turn ordinary fights into crises, and named monsters are a sign that the dream has taken a personal interest in you.
It's turn-based, so you never have to rush, and you can play with just a keyboard. If you'd like to learn the genre's rules first, start with the beginner's guide.

Read: For DCSS PlayersA traditional turn-based roguelike in which Sookuma the bear steals the Dream Crystal from the bottom of the dream dungeon and has to make it back to the first floor alive. It is a grid-based dungeon crawler: every step is one turn, death ends the run (permadeath), and the dungeon is built anew every time.
Yes. There is a free demo on Steam for Windows and macOS. The full game is coming soon, so wishlist it on Steam to hear when it launches.

A lot will feel familiar if you have played Dungeon Crawl Stone Soup (DCSS): lineage and class combinations, faith and unidentified items. Dungeon Sookuma is a separate game unrelated to DCSS, and what is the same and what is different is laid out in the guide for DCSS players. Read: For DCSS Players
It is turn-based, so nothing rushes you, and you can play with just the keyboard. The rules of the genre and tips for your first run are in the roguelike basics guide. Read: Roguelike Basics
That run ends and you go back to the main menu to start a new dream. The dungeon is built anew each time, so every run is a different adventure.
You can save and quit at any time, and it supports Steam Cloud.
If you enjoy it, add it to your wishlist, and Steam will let you know when it launches.
