Gave this a go, really well done. There seems to be a bug in the first lesson already; for whatever reason it's telling me to type the response to the troll in french. If you follow the instructions, it throws syntax and typo errors as it wanted the solution in english. "Show the solution" button provides the output in english as well. Some weird language stuff going on.

Submitted a report and the developer replied and has issued a fix for this french/english problem now. (— Henry V, probably.)
