APL game engine is indeed an unusual thing. I don't know much about APL, and never used it (toyed with J back in the days though). I am really interested in the development process and the challenges posed by using APL for that kind of project. Also, I really appreciate that the ReadMe file doesn't try to sell this project as something more than it actually is - a buggy passion project. Such honesty is, I feel, relatively rare nowadays.

shameless plug, been working a a voxel editor to create voxels that you could use to decorate a home for a a little creature you have to take care of(a la sims). if anyone has some feedbacks, would be happy to take them! https://kamio.ai/studio

A voxel world is a pretty good sales pitch for APL: the weird-looking part is the notation, not the model.

It would be nice to know how fast it is in comparison to a similar voxel engine written in a language like C++ or Rust.

> This started off as a bet with myself that APL notation would provide an easier way to make a voxel game. Did you win the bet?
