11Case study
Mossbury
A cozy online town, in the spirit of Club Penguin.
The client grew up on Club Penguin and wanted a game with that same feeling: a friendly town you walk around, meet other players, earn coins and decorate a home of your own. Not a copy, an original world with its own characters. We built Mossbury, a 3D town that plays in the browser on a computer or a phone, with real accounts, cloud saves and up to 40 players in a world at once.


01What the client asked for
A game inspired by Club Penguin. The parts they remembered were not the minigames on their own but the place: walking into the town, seeing other players, saying hi, picking up a job for coins and spending them on your room.
It had to be its own thing, with original characters and art, and it had to work in a browser with nothing to install, on a laptop and on a phone.
02Getting in
Make a critter
Pick one of the critter species, a colour and a name on a 3D title screen, then a short welcome tour shows you around town.
Accounts and cloud saves
Sign in from any device and your coins, home, pets and progress come with you.
Two kinds of chat
Players choose between ready made phrases only, or typed chat with a filter that hides rude words, links and phone numbers. The rules are shown before anyone joins.
Worlds with live counts
Pick a world before you enter and see how many players are in each one, up to 40 per world.
03The town
Places to go
Town Square, a café, Clover's boutique, The Glow club, Town Hall, the dock and lighthouse, Whispering Woods, Snowy Peak with an igloo, Sunny Shore, and Maple Street with a pet shop, a bank and a picture house. An illustrated map takes you anywhere.
Neighbours with routines
More than twenty townsfolk, from the mayor to the mail carrier, walk their own day, chat with you and like particular gifts.
Day, night and the real calendar
The town follows the clock, with lamp lit rooms at night. Seasonal festivals arrive on real dates, starting with Halloween, and bring limited hats to the boutique.
Music and sound
Each place has its own soundtrack played on real instruments, plus recorded footsteps, splashes and chatter.
04Things to do
Jobs and coins
Work the café counter, forage in the woods and pick flowers to earn coins, then spend them on furniture, hats and gifts.
Fishing
Cast, wait for a nibble, then reel in at the right moment. Six species with sizes go into a fish log, from the dock, the pond or a rowboat you can take out.
Pets and the bank
Adopt a pet from the pet shop, walk it around town and keep it happy with treats. Savings at the bank earn interest every day.
A home of your own
Place and turn furniture, cook, nap, put the radio on and dance. Other activities include sledding, building snowmen, a story with goals to finish, and a film at the picture house with popcorn.
05How it is built
Every model made for it
The critters, buildings, furniture and animals are modelled in Blender for this game, so nothing looks like a stock asset pack.
Multiplayer on Cloudflare
Each world is a live room that keeps players in sync, including their pets, and the same server holds accounts and saves.
Installs like an app
On a phone it can be added to the home screen and opens full screen, and the controls fit under a thumb.
Its own address
Mossbury runs on its own domain, mossbury.fun, ready for players.
★The result
A town people can walk into today.
The client asked for the feeling of Club Penguin and got a game of their own: a living town with friends, jobs, pets and a home to decorate, open in any browser.
It is live at mossbury.fun and keeps growing, with new places and festivals added as the year goes on.
