Git is ubiquitous these days - but it has a pretty steep learning curve! To help people learn how to use it efficiently and intuitively, we're developing an interactive, open-source learning game! It makes heavy use of visualizations, features an (optional) graphical "playing card" interface, and uses real Git repositories under the hood! Storywise, you're a time agent in training, and learn all about how to use your time machine to help people solve their problems. In this talk, we want to introduce you to how the game works, and show you our current progress. We're using the Godot engine, and have a simple, extensible level format based on Bash scripts, which you can use to build your own levels! We want to accomodate both people who are new to Git and the command line, as well as advanced users who are interested in learning more about what's going on under the hood. We'll share what we learned in our playtest sessions, and what's next.
