2D Rigid Body Collision Resolution
From Mario bouncing off a Goomba to two cars bumping into each other in a racing game, dealing with collisions is such an integral part of most video games that we often take it for granted.

Activision’s faulty anti-cheat software
Activision’s blind faith in the infallibility of their RICOCHET anti-cheat software , combined with a buggy and unstable Call of Duty: Modern Warfare II release, has resulted in faulty, permanent, and unappealable player account bans that prevent users from starting even the single-player game. These bans leave…

How a 64k intro is made
The demoscene is about producing cool real time works (as in “runs on your computer”) called demos . Some demos are really small, say 64 kilobytes or less, and these are called intros . The name comes from “crack intros”. So an intro is just a demo that’s small.

Roblox is the biggest game in the world, but is unprofitable
With 380MM MAUs, Roblox probably counts more players than the entire AAA gaming ecosystem, is more played than Disney+ is watched, and is starting to rival smaller social networks in scale. But Roblox has yet to profit. How can it become a business comparable to its operating scale?

Solitaire
I have cited a few games as inspiration for Balatro in the past, but I wanted to talk about one in particular that hasn’t been mentioned much that arguably is the most important. I think if I had some kind of Balatro vision board, solitaire (Klondike) would be right in the middle of it with a big r

Wordle is pretty damn smart in many subtle ways
I love Wordle. I play it pretty much every single day. I also play the portuguese version immediately afterwards too. It is now part of my morning routine. Wordle is one of those ideas that just click and immediately have you wishing you were the one to have them. If you don’t know what Wordle is, just click here and…

Rotoscoped Animation of Filmed Parkour
Hallå! Welcome to my first game devlog. I figured I'd start out talking about graphics, as they are a large source of anxiety for first-time developers. And not without reason! Everyone is a judgy bastard when it comes to how your low-budget game is presented. Oh sure, it's become easier for a solo developer to mask…

What happens if you remove randomness from Doom?
For some reason, recently I have been thinking about Doom. This evening I was wanting to explore some behaviour in an old version of Doom and to do so, I hex-edited the binary and replaced the random number lookup table with static values.

X-COM
X-COM seemed to come out of nowhere. Its release was not preceded by an enormous marketing campaign with an enormous amount of hype. It had no video demo playing in the front window of Babbages, it wasn’t advertised twelve months in advance on glossy foldout magazine inserts, it had no flashing point-of-purchase…
