The Steam Next Fest is upon us, and with it brings a bevy of cozy game demos! Unfortunately, I can’t possibly detail every single one, but I can highlight the developers who reached out to me personally to let me know about their games!
If any of these games catch your attention, go ahead and try out the demo! If you like them, add them to your wishlist since that’ll help them out greatly. Wishlist likes are what drive the Steam algorithm and will determine what gets pushed to more eyes.
As always, I’ve made sure to check them all and am happy to report these games are all human-made!
We do our best not to highlight games that use Generative AI at any level of development or marketing. At the time of posting, these games have not reported or disclosed using Gen AI. Likewise, all articles are written and edited by humans… as evidenced by our occasional errors.
Steam Next Fest Cozy Games!

Lou’s Lagoon
Lou’s Lagoon is an exploration and crafting adventure game where you respond to your Uncle Lou’s distress call, only to find the islands in disarray and your Uncle nowhere to be found. In an effort to find Lou, you’ll help rebuild the community and create a base of your own. Explore by foot to meet the locals and find secrets, or take to the skies with your seaplane to get a different view and participate in some flying challenges. Can you piece together the clues and find your Uncle Lou?
Case Solved: The London Files
Case Solved: The London Files is a noir puzzle game where you tackle several different investigations. Each one is a closed logic puzzle where you’ll collect clues, talk to witnesses, and figure out who the culprit is. It’s a 1960s-style mystery that’s done in a hand-drawn 2D style across 3 different cases.


Woodo
Woodo is a diorama puzzle game where you assemble a scene of wooden pieces to create a bigger image. Find the correct spots for objects and watch the white base of the diorama slowly fill with color and life. Experience a friendly narrator, a gameplay that adapts to your speed, and a bunch of funny characters and silly animations.
TANUKI: Pon’s Summer
TANUKI: Pon’s Summer is a job simulator where you play as a tanuki named Pon who is a part-time mail deliverer for the Post Office. Instead of setting out on foot, you’ll hop on a BMX bike and take a more unique route to getting packages where they’re going. Explore four major towns, each with unique quests and manage packages of different sizes. With the money you earn, you can build and decorate a shrine.


Cozy Marbles
Cozy Marbles is a building game where you create marble runs with a vast assortment of pieces in wood, metal, or plastic. Once you’ve built it up, you can set your marbles loose. Choose the color of your marbles, give them faces, or dress them up in hats for an even livelier race to the finish. Share the runs that you’re happy with and dive into runs created by others. If you’re a Twitch Streamer, it has Twitch integration so you can watch the races with your viewers.
Cat Mail Co.
Cat Mail Co. is a job simulator where you take over an abandoned post office located on a quiet island after the previous postmaster has vanished. You’ll tackle a mountain of undelivered mail by sorting the deliveries and taking care of customers. There are no timers or penalties and you can play solo or with up to four people. Sort things by day and experience a magical mystery by night.


Cozy Game Restoration
Cozy Game Restoration is a simulator where you’ll take damaged game cartridges and restore them to their former glory. Each game has different things that need to be remedied, whether it’s drawn on, covered in stickers, has a cracked case, or something else. Each game has procedurally generated issues, which means you can continuously play. You’ll get the games in mystery boxes and won’t know what you get until you open them. Can you collect all 108 titles? Each restoration will complete collection-based quests and will reward you upon completion.
Cozy Builder
Cozy Builder is a sandbox building game with farming and crafting elements. You’ll design a château from modular architectural pieces and be able to pick every detail, both inside and out. In between design phases, you’ll harvest grapes from your vineyard and create artisanal wine. By exploring the land, you can find resources to create rustic goods and enhance your wares.


One Coin Museum
One Coin Museum is a fishing and exploration game where you’ll play as Toadz, a little frog with big dreams of opening a sea museum. Explore the ocean depths with a claw attached to your ship and pull up treasures to display in your museum.
Abracademia
Abracademia is an idle life-sim that puts a magic school at the bottom of your desktop. You’ll create your own little wizard, pick their traits, and decide what kind of magic you want them to lean toward, then set them off on their way. Whether you want to manage every little detail or idly let them progress, you have the option to do either. It’ll take you across five years of schooling where your character will attend classes, join activities, learn spells, and take exams.

Which of these cozy game demos are you going to try out? I’d love to know in the comments!
