Sticker DECO Steam: Kawaii Y2K Scrapbook Game

Sticker DECO is a cozy kawaii scrapbook game on Steam, and honestly, it is the most Y2K thing I have played all year. You collect stickers, peel them onto the pages of a ring binder, and trade the doubles with a crowd of quirky animal friends. That is the whole loop, and the art direction makes it feel exactly like the sticker book that lived in your school bag, the one with the puffy hearts and the glitter you were too scared to use.

It comes from Studio Mimosa, a small Japanese indie circle that makes cute games and sells real stickers and goods on the side. It launched on October 30, 2026, App ID 4566980, for Windows, at US$5.39 with a 10% launch discount off US$5.99. When I checked on the morning of November 8 (BRT), Steam showed 100% of 16 user reviews as positive. Tiny sample, very warm start.

A sticker binder you can actually finish

The store pitch is simple: relive the excitement of the sticker books you loved as a kid. What sells it is the feel. The table is red gingham, the binder has chunky gold rings, the pages are cream with a soft grid, and every sticker has that thin white die-cut border that makes it read as a real object instead of a UI icon. Lowkey, that border is doing a lot of the work. It casts a tiny shadow, it catches the eye, and it makes a fluffy dog sticker look like it could be peeled back off.

There are no time limits and no fail states. You decorate at your own pace, and the game is happy to let a page sit half done for a week.

Mouse-only decorating that feels tactile

Decorating is all mouse. You drag a sticker out of the palette on the left, rotate it, nudge it, and change its layer order so a bow sits on top of a kitten instead of under it. The binder has 10 background pages you can recolor and restyle to match the mood, and the collection runs past 2,000 stickers: sparkly, dreamy, cool, food, planets, tiny animals, and a lot of very round fluffy things.

The little details are why it works. Pages have a slight paper texture, the palette is all candy pink, butter yellow and baby blue, and stickers cluster the way real ones do when you run out of room. It scratches the same miniature arranging itch as Hokko Spaces, just flattened onto paper. When a spread looks right, a built in camera button snaps it for sharing, and the studio openly welcomes streams and monetized videos.

Fifty animal friends and trades with personality

Outside the binder there is a cute top down town map where you meet more than 50 animal friends. They are drawn like polaroid portraits in a little album: a dog girl with a coffee cup, a poodle in a pink apron, a gorilla in a white sweater, a frog in a red scarf, a poodle in a plaid shirt. Each one has a name and a personality, and that personality matters.

Trades are the clever bit. The outcome changes with your friend's taste and the sticker's rarity, so you start reading people: this one likes sparkly, that one wants food, this one only cares about rare pulls. It turns collecting into a soft guessing game instead of a gacha grind. Steam also lists online co-op and multiplayer, and the studio's online help page covers friend invites and rankings, so you can show off collections with real people too.

The design is almost wordless on purpose. Text is kept to a minimum, so the joy reads instantly even if you never open the menu. If you liked the soft Japanese everyday mood of Danchi Days, this is the same nostalgia in sticker form.

What our clip shows

Three takes cut from the official PV_v2 trailer, with its own audio. First, a cream scrapbook spread filling up with stickers before the page color picker slides in. Second, a quick flip through fully themed spreads (a starry navy page, a sticker grid, a spooky page) landing on the animal friends album. Third, a trade with a little dog friend, stickers flying across the table. No logo cards, just decorating and trading.

Price, platforms and what to know

Tags lean Casual, Indie and Simulation, and the specs are featherweight.

The Steam page carries no AI content disclosure. To be upfront, the purple hover sketches on this page are Voidge drafts made with AI image generation, not art from the game.

Who makes Sticker DECO?

Studio Mimosa is a small Japanese indie circle focused on kawaii games, and it looks like a very small team, with the creator credited for drawing around 2,000 stickers and 50 characters. On X, @sutajiomimoza (around 1.1k followers, posting in Japanese) shares art, merch and updates.

Bottom line: if you ever traded stickers at recess, Sticker DECO is an easy recommend from me. It is cheap, kind, and the palette alone feels like a pastel time capsule.
