DemonStudios Ltd is a one-man indie game developer based in the UK, making games for iOS, Android, PC, Mac and SteamOS/Linux.

Its founder, chief game designer, lead programmer and preparer of tea is James Shaughnessy. James first created the game Gravitation back in 1998 on a Net Yaroze, which made it onto the coverdisk of the Official PlayStation Magazine. Then, after 11 fantastic years working at Codemasters on various titles such as Pro Race Driver and Operation Flashpoint: Dragon Rising, he left to return to his indie gamedev roots and founded DemonStudios Ltd.

NEW! 3D Spinner - Virtual 3D Fidget Spinners on iOS and Android! Click the icon to go to the 3D Spinner page!

There are lots of games in the works and countless different prototypes, but the first two games to be released are Lead Wars (an iOS exclusive), and due to popular demand an official sequel to the Net Yaroze game Gravitation, Super Grav - out now on mobile and just launched on Steam! The Steam version is the most advanced as the online Leaderboards support replay attachments so you can show off your record-breaking skills to the world!

Games released & in-development:

Lead Wars is a simulation of a real life old-skool pencil and paper turn-based strategy and skill war game. You can play against the CPU, with a friend, or battle online head-to-head against people from around the world, and is out now!

Super Grav is out now on mobile, and launched November 7th on Steam! 10% launch discount until 14th November so get in there quick!

Gravitation is a full updated port of the 1998 Net Yaroze game, playable here - the full game for free! And now supporting 4 players!

XJ is a 2D off-roading sim coming to iOS and Android later this year - a very early pre-alpha demo is playable right now in your browser (uses WebGL) which while far from finished should hopefully still be fun if you like this sort of game!

Fliptomino is a work-in-progress tetromino-flipping puzzler. A very early alpha test is playable in your browser right now (just click the image below! to play)

Match Four is a Connect-4 style mini game for two players that was hidden in Gravitation (v1.3) on the PlayStation Net Yaroze version. And possibly in the latest PC and mobile versions of Super Grav too… :) Now ported to Unity using the original graphics and sound, it's available to play free here right in your web browser! (uses WebGL and currently runs on desktop PCs only)

Logograph will be an App which uses the Logo language allowing you to draw complex shapes in 3D space, learn a bit about programming, and create some beautiful mathematical art. Development is on standby but I plan on rekindling this at some point.

A page for the BBC micro:bit - currently featuring a handy Rubik’s Cube / Stack timer program you can try out in an emulator or on a real micro:bit, and also a brake/tail light for your bike, scooter or skateboard!

And here I am unwinding in Wales with a relaxing drive in an E30 M3 after a long day of game development :)
