While on a walk with my wife and puppers Benji (hence the original name "Benjiwalk") we came up with a good idea to test out GGEZ. Here it is after a few hours of work. I was brand new to GGEZ and still only about a week into learning Rust.
To build, clone the repository and run cargo build or cargo build --release. If you want to build and run, do cargo run or cargo run --release. The framerate is much better with the --release flag.
To play, use arrow keys to move Benji around the screen. He likes to pee on everything, but you will only get points for peeing on fire hydrants. Use space to pee on something, arrow keys to move, and return to start a new game. My high score during testing is 1656.
