This is a simple maze game. You can play it here https://nhatcher.github.io/amaze/.
This is a javascript/HTML port of a very old game I did in C back in ~1990.
It uses a recursive backtracker algorithm as in https://en.wikipedia.org/wiki/Maze_generation_algorithm. Of course back then I had no idea what that was.
I had just finished reading Roger Penrose's The new emperor's mind and I was crazy about AI. I wanted to create a computer program that was able to create things. Somehow me and my friend Iván came up with this shit.
I felt pretty proud at the time...
