May 17th, 2021Site Refresh

As part of the process of moving all of my sites to the same server, I decided to give this blog/portfolio website a bit of a facelift. Wordpress is gone (It always seemed a bit heavyweight for my needs, and the constant security updates it required were a concern). Instead: the new site is purely static HTML, generated offline.

In order to accomplish this without having to learn a bunch of new web-tech, I wrote a simple text processing system using Lua, inspired by how PHP let's you mix code and markup in the same file. I've shared the code on GitHub if anyone else wants to use it: LHP.

March 8th, 2021Redirection is now Open Source

After 4 years, Redirection (the puzzle game I developed and released on Steam in 2016) is now open source! Here's a link to the complete source code on GitHub:


This release is inspired by id Software's historic practice of open sourcing their games a few years after release (a practice they sadly no longer follow), and the vibrant community of ports and mods that followed in their wake.

Like those releases, this code release still requires a retail copy of Redirection to run (currently on sale!), and is licensed under the GPL so that any changes people make stay available for the community. I'm excited to see what people do with it!

December 14th, 2020New Game: SKYBRAWL

Last week I once again participated in #7DFPS, the game jam that challenges you to produce a complete, first-person game in one week. As I’m now working on a first person shooter in my dayjob, I decided to create a different kind of first-person game this time: an arcade flight simulator.

Like Tank Commando 3D I opted for a distinctive 1-bit art style to keep the art workload down, but unlike that game, I decided to build this game in Unity instead of using my homegrown engine. The result is a fast, frantic, arcadey dogfighting sim that’s surprisingly addictive! Something I’m particularly happy with that I wasn’t able to add last time is the sound design, especially the lovely Doppler flyby effects that came built-in with Unity!

You can play SKYBRAWL (and see some video and screenshots) in your browser, at itch.io:

December 20th, 2018Now Available: Redirection for Android!

Good news, robot fans: My 2016 puzzle game, Redirection, is now available for Android! It features the full campaign from the PC version, with an all-new control scheme optimised for touchscreen devices. Click on the logo below to check out the game on Google Play:

In addition to this release, the PC and Mac versions of Redirection on Steam and itch.io have been permanently reduced in price by 50%, so there's no better time to go and rescue some Robots!

October 28th, 2018New Game: Tank Commando 3D

Last weekend I took part in #7DFPS, the game jam that challenges you to produce a complete, first-person game in one week. First person shooters have always been my favourite genre of game, but I’ve never had a chance to program one, so this was a real delight for me.

To keep the workload manageable, I opted to build a stealth game about sneaking around and blowing up tanks, with a 1-bit art style inspired by Battlezone and Return of the Obra Dinn. These choices meant I didn’t need to create any textures or character animations, which allowed me to focus my time on movement, gunplay, AI and level design. The result is a surprisingly addictive and replayable shooter with a very distinct design!

You can download Tank Commando 3D (and see some video and screenshots), for free, from itch.io:

January 15th, 2018From the archives: Revisiting my early-2000s Half-Life levels

When I was a younger, before I discovered programming, I was really into level design. Specifically: I was really into designing Half-Life levels. Over the years I made dozens of small maps, but the only ones I released were three popular maps for the Sven Co-op mod. All three were included in official releases of the mod, and remained so for many years.

However: time passed, and in later versions the maps were removed to make way for newer levels. So, in the interest of preserving these files, I’ve decided today to re-release them in one handy archive: Click here to download it!

All the maps require to run is a copy of Half-Life (Update: I’ve now been informed you don’t even need Half-Life! Though you really should own the best PC game ever made) and the free Sven Co-op mod. Both of these are available on Steam, and there’s step-by-step installation instructions inside the zip file.

Working on these maps was some of the most fun I've ever had working on games, and it inspired me to seek out a career in the industry. If you enjoy playing them just 1% as much as I did making them back in the day, then they'll be well worth your time. If you try the maps and have any feedback or thoughts, or just want to reminisce about early-2000s modding, I'd love to hear from you!

May 1st, 2017ComputerCraft is now Open Source

As promised in my last post, ComputerCraft (the popular Minecraft mod I’ve been working on since 2011) is now open source! Here’s a link to the complete source code on GitHub:


With the source code available, people other than myself can now work on updates, fix bugs, and add new features. I’ll still be reviewing pull requests and making releases, so this could mean ComputerCraft is updated more regularly and with more features than it has been in years. I’m looking forward to seeing what people come up with!

April 24th, 2017Life Update

Hello everyone! It’s been a while since I launched this blog, so it’s time for a life update! (This an elongated version of a series of posts I made on Twitter last month)

A month ago I started work at Frontier Developments, working as a Senior Programmer on a very exciting unannounced project. After three years as a full-time Indie, scraping by financially and making everything by myself, it’s nice to be part of a team making something big again.

Obviously, with a full-time job, I now have less free time to devote to my own projects, so here’s how I’ll be splitting my time between them:

Firstly: I’m currently putting the finishing touches on a new version of Redirection for Android and iOS. At the time of writing, it’s almost complete, and I should be able to announce a release date soon. The game works really nicely with touch controls and a lot of people have requested a mobile version, so I’m hoping it does well!

Alongside Redirection, I’m also devoting more time to my next, still-untitled game. I’ve teased this a bit on twitter over the last year or so, but the only thing concrete I’m ready to say at the moment is that this is the spiritual successor to ComputerCraft you’ve all been waiting for.

As for ComputerCraft itself: with less free time, something had to go, so after five years working on the mod alone, I’ve decided to hand development over to the community. Working on ComputerCraft has been an incredible life-changing experience, but five years is a long time to devote to one thing, and it’s time to hang up the pickaxe. The complete source code will be posted on GitHub soon.

Finally: I’d like to thank everyone who supported me and my work during the 3 years I worked as an indie developer. It’s easy to look at returning to employment after being your own boss as “giving up”, but I don’t see it that way at all: I’m really proud of the projects I worked on, and that hasn’t changed just because they didn’t prove successful financially. I would still recommend to any game developer interested in making their own games to give it a try if they have the means: it teaches you so much about your craft, and there’s no feeling like seeing a game you made sitting on your Steam list and knowing players are enjoying it. If I had the chance, I’d do it again for sure, though I might not release a puzzle game into a crowded market this time!

January 23rd, 2017Hello World

Welcome to my new portfolio website! I’ve been meaning to set one of these up for a while, and now that Redirection is released I’ve finally had the time to do so!

The primary purpose of this website is to provide a central place to showcase my portfolio of games and mods I’ve worked on over the years. I also intend to use it to post longer articles and announcements that aren’t appropriate for computercraft.info and would get lost on twitter.

The other reason for setting up this site is that I’m currently on the lookout for freelance work. So if you have a project that you think I’d be a good fit for, check out my portfolio and get in touch!
