It's nice to see C2 being used in education. But it is kind of backwards that they're using such an old version - they're missing out on WebGL shaders, memory management, functions, websockets, pathfinding, full state save/load, syntax highlighting and autocomplete in expressions, line-of-sight, geolocation, regex expressions, and innumerable bug fixes, all of which would probably be useful in teaching. Still, education institutions tend to be on slower software update cycles.
