Title is incorrectly capitalized, should say “Playdate”.

Considering that it only updates 1/6th of the screen, the game is really running at 8 FPS. Still looks great though!

And I really like the "two complete rendering engines working in tandem".

Good article and interesting technical description. Stays on the side of "proud developer keen to share details others would find interesting" and away from the "I made a game and here is my blog to advertise it". I do like hearing about Playdate development and wish I had one. There is lots of other Doom-like games out there with decent descriptions of the ray casting algorithm but the additional tweaks you made for the platform are fascinating.
