I'd love to see this combined with the author's fork()-less implementation of ps to make a (almost) fork()-free implementation of psDoom.

Seriously though, this is really cool

It's unfortunate that stty requires forking. Maybe the next project will be to use bash and rowhammer to call the necessary ioctls to do it without forking.

Only 300 lines of code, impressive! I love this.

And to think, that my own bash scripts spend 300 lines just parsing various command-line options, while instead I could be showing this game... :-P

Beautiful. Correct me if I'm wrong, but this looks like a bash version of https://lodev.org/cgtutor/raycasting.html

Edit: ah, just noticed this is in the readme :(

I wonder if texture mapping this would look good.

Imagine a TUI where you need to navigate a literal maze of options

She has been brainstorming how to handle texture mapping within the performance constraints of doing it in bash for a week now (long before she actually got this working) and so far we've come up with some hypothetical ideas but she has not tried any of them yet. Maybe tomorrow...
