Studio Mimosa is excited to announce that the Steam store page for our 2D sticker book simulation game, Sticker DECO, was published on Friday, April 3, 2026. We are sending this press release in the hopes that you might feature it in your news coverage.
Based on the theme of "The excitement of those days when I always wanted to trade," this game allows players to decorate their sticker books to their heart's content and experience the joy of "trading with friends" that they dreamed of as a child. Additionally, we will be participating in Tokyo Game Dungeon 12 on May 3, 2026, where a playable demo of the game will be available.
■ What is Sticker DECO?
The "sticker books" we were all obsessed with back in the day have become a cute and stylish game. Slap on your favorite stickers and design your very own special pages. Why not gather even more "Kawaii" by successfully pulling off thrilling sticker trades tailored to your friends' preferences?
■ Key Features
Infinite Customization with Just a Mouse!
Freely decorate your collected stickers across a 10-page sticker book. You can customize the book's cover and backing pages (backgrounds), and decorate up to 5 separate books. All operations, including placing, rotating, and changing the overlapping order (layers) of stickers, can be done intuitively with just a mouse.
Over 1,000 Stickers & Exciting Seasonal Changes
Discover over 1,000 types of stickers, including sparkly, dreamy-cute (Yume-kawa), and cool designs. Stickers can be picked up on the map, traded with friends, or obtained via the in-game coin "Gacha" (*There are no microtransactions/real-money purchases). The available gacha and stickers change depending on the in-game season and weather, such as sunny, rainy, or snowy days, bringing new discoveries every day.
Deep Sticker Trading with Over 50 Animal Friends
Over 50 quirky and cute animal friends appear on the map. Each friend has different personality traits, such as prioritizing "Cuteness" or "Coolness." Enjoy a puzzle-like trading experience where you read their preferences and offer the right stickers. The game also features strategic elements, like aiming for "Combo Bonuses" by matching specific categories, or trading repeatedly to raise your friendship levels.
A Non-Verbal, Universally "Kawaii" Experience
The game features a non-verbal design that minimizes text information. It is designed so anyone can play intuitively without reading tedious instructions. Once you've created your ultimate page, use the built-in camera button to take a screenshot and share it on social media!

■ Developer's Comment
"I started developing this game wanting to recreate the childhood memories of showing off and trading stickers with friends, the slightly lonely feeling when there was no one to trade with, and the excitement and longing of those days. In addition to the pure joy of decorating and figuring out how to combine over 1,000 types of stickers, I've packed in the fun of a simulation game, such as the depth of trading by guessing the other party's preferences and presenting your own stickers. Whether you share these nostalgic memories or simply love collecting cute things, I hope you enjoy decorating to your heart's content on your PC."
