The code demonstrates how to make a simple game in the Zig programming language and the Raylib library. The levels are designed in a custom keyboard-driven level editor developed in a separate project by the author.
The game itself is a platformer drawn with colored rectangles where the player has to collect rectangles using some purple bouncy "lava" tiles and reach the exit. It's simple, and the idea is a bit clever.
The distribution, however, does limit the potential audience a lot, because it requires the Zig toolchain in a Linux or BSD system running Xorg to build and run (Even then, I sent this project to a friend running Manjaro and we didn't manage to run it there). I wonder if one could build a project like this on Windows under WSL and run it with VcXsrv.
Thanks for giving me an excuse to install the zig and raylib packges on my Arch install! They seem to be interesting projects and I might play a bit with them someday.
