Hello!
https://aquasition.itch.io/raycast-demo
I've been making a raycaster demo on PICO-8, and it's been a lot of fun developing it! Right now, I'm working on sorting out sprite viewing, as I can't seem to get it right, due to issues determining whether I can see the sprites or not! I've managed to make maps in PICO-8's Lua code directly, have frameworks for the weapons, and can raycast the walls effectively!
