I recently discovered an odd first-person maze game called “Lair of Squid” built into my HP 200LX palmtop PC, released in 1994

Then I found the author. Here’s the story of how this quirky Doom-inspired title came to be: https://arstechnica.com/gaming/2024/07/how-i-found-a-forgotten-squid-based-ode-to-doom-on-a-1994-palmtop-pc/

Why 1994’s Lair of Squid was the weirdest pack-in game of all time

The HP 200LX included a mysterious maze game called Lair of Squid. We tracked down the author.

@benjedwards Andy mentioned Everett Kaser - I've heard of that guy before! One of DOS shareware's somewhat more prevalent names, still in business to this day selling updated versions of his logic puzzle games. That's a really cool connection.
@wildweasel yeah, and his Hearts and Bones game on the 200LX is excellent
