Rat soldiers in First World War uniforms holding a trench in the mud beneath the boots of human soldiers

Mud & WhiskersThe Great War Below

The rats have their own Great War, and it is fought in the mud below yours. Dig the trenches, keep the runners moving and hold the line — a burrow is only taken on foot.

Coming Soon

A pixel-art cutaway of a meadow: ants carrying a leaf along the grass line above, and below the soil a nest of tunnels, chambers and a clutch of white eggs, with a toadstool, a stream and a frog

Beneath the Grass

An ant colony that lives whether or not you are watching. It forages, digs and buries its own dead without you — but a colony left to itself only survives. Meadow, forest and desert, and no ending: only how many ants you keep alive.

The Studio

I'm Marius. I make games you play in a browser tab — no launcher, no download, no account, no price. You click a link and you are playing. Angry Marius Games is the sign over the door; behind it is one person in Denmark.

Why browser games

Most games want something before they give you anything. An install. An account. A launcher that spends six minutes updating itself before you are allowed to be bored. Every one of those steps quietly loses someone who would have enjoyed the game. A browser game asks for a click.

That constraint shapes everything I build. A game has to be interesting within seconds, run on a five-year-old phone, and survive being opened on a train. Those turn out to be good rules to design under. They rule out an enormous amount of padding.

Why I make them

I write business software for a living. It is useful, and it is not very exciting. Games are where I learn the things that job never asks for — and I learn them by building, not by reading. You cannot read your way into knowing how a system feels after ten seasons. You have to build one and watch it go somewhere you did not expect.

How they are built

I don't write most of the code by hand. I work with an AI: I decide what gets built, why, and how it should feel to play — and a lot of the typing happens somewhere else. It is the reason someone with a day job can finish a game at all.

What comes out is plain HTML, CSS and JavaScript. No frameworks, no build step, no bundler. The file I edit is the file your browser runs, so a fix takes minutes instead of a deploy pipeline. It is an unfashionable way to work and an unreasonably durable one — games built like this still run years later, because there is nothing underneath them to break.

Saves, money and data

You can play everything without an account, and your progress is saved in your own browser. The catch is that it only lives there: clear your cache, switch to your phone, and it is gone. Make an account and your save follows you instead.

The games are free and stay free. Revenue comes from my own banner system, sold and served in-house, so no third-party ad network gets to decide what appears next to the game — and if you want to advertise, the same account buys the space. I don't sell player data, and I'm not going to. I also read every message sent through this site.
