Time travel in Braid
I bought Braid on the promise of lavish visuals and neat puzzles with temporal mechanics, and on this basis I was rewarded. I found some frustration with the controls, which I eventually traced to dodgy keyboard drivers - the game wouldn't register the up or down arrows while I ...

Raytracing a Black Hole
It's now clear I'm on a Black Hole binge (I can stop when I want, by the way). They're endlessly fascinating. My recent interest was in particular focused on simulating visualizations of the Schwarzschild geometry. I was preoccupied by the problem of generating a decent accurate representation of how the curvature of…

I Know This – Hack Jurassic Park’s Security System
“I Know This” is a game I made for the Global Game Jam 2015 along with Gavin McCarthy (art, design), Adam Axbey (sound effects) and Matthew Simmonds (4mat) (music); I did programming and design. The name we chose for the team was Two’s Complement .

Procedural City Generation
Since seeing the city generation from the shelved Introversion Software game “Subversion” in action , I’ve wanted to to try writing a basic procedural city generator myself. The developers followed a method described in Parish and Müller’s paper: Procedural Modelling of Cities (2001) . The paper is well-written and…

Classic NES Series Anti-Emulation Measures
Some of you may remember a series of peculiar Game Boy Advance games that came out over the course of 2004. In stark contrast with the usual dark grey cartridges with colorful labels, a set of light grey cartridges with simple labels were released containing games ported from the original Nintendo Entertainment…

Intrusive lists in Doom 3
Doom 3 was released in 2004, which I can't believe was a decade ago. Great game, atmospheric and scary, and a worthy successor of the first two games in the series. Several years after the initial release, in 2011, Doom 3's source code was published on Github. It can be fun to poke around the repository to learn how…

Why movies look weird at 48fps, and games are better at 60fps
Let’s end this debate once and for all. Humans can see frame rates greater than 24fps (although plenty of people will argue that they can’t on the internet). I’ll explain more in a future post if necessary, but let’s take that as read.
