I really like the approach and the visuals. I almost never think of Git visually and this opens a whole new dimension for me. I'm looking forward to discover techniques and workflows outside of my everyday patterns. Thank you for sharing this with the world.<p>However, the interface is often confusing. For example, I'm not sure what to do with the avalanche of dialogs at the beginning. So I just navigated to the earliest '1' button and pressed that. Also, the "goal" graph at the beginning of each exercise disappears, and I don't know how to recall it. Finally, the goal objectives can't be displayed at the same time that the console is active, and "help level" restarts the entire level description. It would be nice if both the goal graph and the list of objectives were both visible during the exercise. (If this is indeed possible, I obviously missed it.)
