I’ve done a lot of game jams and have used many engines and frameworks in these jams. They all have pros and cons, but lately, I’ve been using fantasy consoles as my platform of choice, and I think you should too - they are fantastic for game jams.

What are fantasy consoles? In short, they are virtual consoles that mimic retro computers and their limitations, but also provide a complete game development environment. Within the same application, you can draw simple sprites, compose chiptune music and sound effects, and write code using a limited API. Its severe limitations are also its appeal; it’s not only a piece of cake to pick up and learn, but the limitations encourage creativity. PICO-8 is the most popular, but there are many others to choose from.

One of the most important factors when choosing a platform for jams is development speed. You want to be able to put something playable together as quickly as possible, as time is the scarce resource. Here the popular engines do very well; Unity, for example, has a lot of functionality built-in, or easily accessed via its asset store, so you can quickly piece something rough together.

Fantasy consoles represent an alternate approach - with limitations and fewer tools at your disposal, there is less time wasted in choosing how to make your game and more time on focusing on gameplay and making something fun. It’s easy and quick to put together something playable, so you can start iterating and polishing on top of a solid base.

For a while there was this idea that music was the universal language. Our human languages may be mutually unintelligible but we could always enjoy each other’s music. Music is such an important part of our cultures that we even sent it out on the Voyager golden record.

But is it really as universal as we thought? Even hearing some of the songs in the golden record, they could sound beautiful yet alien to those of us accustomed to Western music, like this haunting Navajo chant:

And then consider how different everyone’s musical tastes can be, how they are shaped by teenage experience in particular. The kind of music we listen to as adolescents usually sticks with us for all time.

Random level generators are great fun to make; there’s nothing quite like coding an algorithm that creates endless variations of maps and dungeons.

A typical random map generator might place rooms randomly around the place and connect them with corridors. Then the map might be filled randomly with inhabitants - monsters, treasure, NPCs and so on. This is simple and effective, giving players unpredictable yet interesting encounters in games. It’s an evergreen approach starting from rogue (1980) all the way up to the latest indie dungeon crawlers.

This can seem backwards though. One problem is that the layout often seems artificial; there’s not much reason or purpose for the rooms and the connecting corridors. Real locales would be filled with inhabitants, with paths connecting important destinations together. The paths are like arteries; they are inextricably linked to the design of the whole place.

So I thought a fun experiment would be to make a random level generator that builds such a map via simulation: fill it with virtual inhabitants, who need to go from A to B, find out what paths they need via pathfinding, and create the paths based on travel patterns. Let’s see how this goes!

First, I start with a simple “village” generator - just a bunch of buildings scattered randomly around the place.

I’m a sucker for level design and design patterns, so when I came across this article (and paper) called “Level Design Patterns in 2D games”, I had to read it! Unfortunately it’s a bit wordy, so I thought I’d summarise it and throw in a bunch of pictures! Enjoy!

Hover over the images to read an explanation for each example!

Recently I restored the font used in C-Dogs SDL to the one used in the original C-Dogs. The reason why they were replaced in the first place was because the original graphics weren’t open source, so I was looking for alternatives. A few years back the author of C-Dogs agreed to open source the original graphics, and I’ve only just gotten around to restoring the font.

But that’s not what this post is about! I want you to take a look at the C-Dogs font:

It’s actually a pretty neat font. Most of the letters are just 3x5 pixels (some wider or taller), but with a few tricks they look super legible for their size. Here I’ll show you some of the tricks used to make pixel fonts really legible.
