Mad House — Usborne Creepy Computer Games
Via Hacker News I learned that UK publisher Usborne published free PDFs of their 1980s Computer Books, some of which I remember working through on my Commodore 64 as a child.
These were so great! Beautifully illustrated books with fun projects made up of code you could type into your own machine.
I remember playing "Mad House" typed in from the 1983 book "Creepy Computer Games", so I fed that PDF into Claude and had it build an interactive version of that game in JavaScript and HTML:
Build a vanilla JS artifact that exactly recreates the game Mad House from this book, make sure it's mobile friendly and has a suitable retro aesthetic
