Wow that's great to hear! Seriously, really glad someone found it useful. That's the entire reason I built it.

Levels support a "disable-map" that will prevent certain commands from executing. I somewhat foolishly assume that users only learn commands as I introduce them, but I should go back and lock down some of the levels.

Also, I'm working on a way to compare trees without the ghosted nodes --- it's a bit tricky, but if anyone loves graph traversal and would love to help, chime in on github!
