I'm gradually going through my older code, updating projects I think merit some love. A year ago now I implemented a simple maze generation algorithm, the algorithms aim is to completely cover the area of the maze and the maze should have no isolated areas, you can get from any location in the maze to any other.
Being as the API for Raylib is amazingly stable - even given all the work that goes on behind it, the only actual "updating" needed was changing FormatText to TextFormat (which ironically I'm now not using) While there I added a few minor tweaks and fixed some comment typos, between the previous post and the comments in the code you should have everything you need.
Enjoy!
