DOOMQL is a novel project by Peter Gostev that uses SQLite as a game engine to create a Doom-like game. The blog discusses the creative implementation of movement, collision, and rendering through SQL queries within a Python terminal script. It describes the process of setting up and running the game, as well as creating a custom HTML+JavaScript app that interfaces with the game's SQLite database using Datasette. The post showcases innovative uses of SQL and AI in game development.
