I coded this and the Rust program found in the dungeoncrawlecs repository by following along in Hands-on Rust by Herbert Wolverson.
It's a simple dungeon crawler game that uses the up, down, left, and right arrows to move around a character. Game art was sourced from: Buch; Melissa Krautheim; and Dungeon Crawl Stone Coup under CC Zero license.
I chose to do this project because--while I have some experience coding in a major game engine like Unity--I wanted to learn how to build a game from the ground up in Rust. By implementing this simple project, I learned more about using crates and modules, organizing imports with a prelude, using "programmer art" as a placeholder for some of the finer artwork linked above, rendering player, camera, and map elements, and connecting the player and camera.
