Game Font Forensics
I hold VileR's work on int10h.org in high esteem, given its exceptional quality. As someone whose initial exposure to computers was through IBM PCs, I find VileR's website to be a treasure trove of IBM PC fonts, BIOS fonts, and related resources.
Inspired by IBM PC games from the 1990s, I aspired to create my own invaders-like game. However hindered by limited access to computers and limited computer programming knowledge, the most I could manage to make were a few text-based adventure games. Although 25 years too late, during the COVID-19 pandemic, I revisited this dream and spent a weekend writing my own Invaders game[1] using HTML5 Canvas.
Initially, I used CanvasRenderingContext2D: fillText() to display text (current score, info screen, etc.). However, dissatisfied with the text rendering quality, I began looking for IBM PC OEM fonts online and came across the Oldschool PC Fonts[2] on int10h.org. I downloaded the font packs from the website, used a Python script to convert them to bitmaps[3] (arrays of integers), and then used the bitmaps to draw text on the canvas, one cell at a time, to get pixel-perfect results!
I eventually switched to a different font pack called Modern DOS[4] developed by Jayvee Enaguas. Nevertheless given how extensive VileR's website is and how convenient the font preview tools[5] on the website are, int10h.org remains as my go-to website whenever I am doing any type of retrocomputing work for fun.

Show HN: Auto-play algorithm in action for my single-HTML-page invaders game
The entire game is written as a single HTML page, so using the "View Page Source" feature (if available) of your web browser shows the entire source code of this game. The auto-play algorithm is present in the function named autoMove(). It is about 100 lines of code that decides the next move of the player.

Why I started (and stopped) making games
I wrote an invaders-style game last year: https://susam.net/invaders.html
It was, in fact, a childhood dream of mine to write a game like this. However, the little GW-BASIC programming I knew and the very limited access to computers I had then was insufficient to write anything more sophisticated than simple text-based input/output programs. Although 25 years too late, writing this little game fulfilled that childhood dream of mine!

Andromeda Invaders: A retro-style game written in HTML5, Canvas, and Web Audio
An update regarding this thread:
I received a pull request that adds pixelated rendering to the game canvas: https://github.com/susam/invaders/pull/4
I have merged it now. Thank you, everyone, for the discussion regarding retro-style rendering on this thread.

Why is open source game-dev not a thing?
My open source game projects are generally one shots, e.g. https://github.com/JustinLloyd/invaders requiring very little in the way of updates because I don't have the time to commit to ongoing maintenance.

I wrote a 1980s-arcade-style invaders game to fulfill a childhood dream
These sorts of games are incredibly fun to write in modern languages, especially if you are given a canvas and the ability to blit graphics around without much concern for memory usage or blit speed.
Obligatory self-promotion: https://justin-lloyd.com/ which is my C.V. site that includes a 1970's-era space invaders style game based on the portable Galaxy Invaders 1000 game.
https://github.com/JustinLloyd/invaders
"Invaders from 78" is written in Typescript, implements a small ECS framework, uses Pixi for canvas rendering, and is event driven. No audio because, well... it's a C.V. website. It also doesn't work on mobile because the audience numbers for mobile visitors to my C.V. website is near enough zero that it would be wasted effort. Please excuse any front-end sins I may have committed because I generally don't do front-end web dev.
