I logged into the comments to say the same. I'm absolutely loving the game like tutorial. "Just type stuff till it works" it's fun, you can't really mess stuff up.

My feature requests would include: a) a hint system. if I don't get it three times I'd like to be able to give up. I know it's open for abuse, but I'm a grown man and understand that I'm only cheating myself. end of the day I still want to learn it.

b) a link from each concept to the reference documentation of the function I've just used. So when I've finally used [* $near spoilers redacted*] let me see the actual documentation for $near if that's possible I guess. I'm not sure how complete the Mongo docs are. My reasoning being that I'd like to see the rest of the ways I can use the command.

Short answer: I love the tutorial & thank you.
