The studio

A tiny studio with a galaxy-sized imagination.

Purple-Galaxy Studio is the games brand of Purple-Galaxy, an independent company.

The studio desk under a round observatory window open on a purple spiral galaxy: a hex-grid battle on one screen, comic panels on the other, sketches and a mug of coffee.

Our story

From software to worlds

Purple-Galaxy was founded in 2025 as a software company, building websites, mobile apps and business tools for clients.

The studio is where it builds its own games. Stellar Frontier, a tactical space strategy game, and Jack Decode, a cozy comic-book detective game, are both in development, with a third world taking shape behind a closed door.

Mobile-first, multilingual and independent: the games ship in English, French and German where it makes sense, with no publisher and no shareholders between us and the players.

Founder, developer & game designer

What we stand for

Four promises

Made by players

A tiny team that plays its own games every day. We build with modern tools, AI and procedural generation included, and keep testing what they produce until it plays well. If it isn't fun, it doesn't ship.

Fair by design

No pay-to-win, no dark patterns. We respect your time, your wallet and your data. Jack Decode has no ads, no account and no in-app purchases; this site sets no cookies.

Play your way

Short sessions, offline play where it makes sense, and games in your language. A frontier station that works while you sleep; a detective case that fits a coffee break.

Independent

No publisher, no shareholders. Just us, the players and a lot of coffee. Decisions are taken for the games, not for a quarterly report.
