good job on creating this! one thing i'd improve is to have a way to jump to the harder sections without doing the easy ones if you are already good at sql. one other thing is probably showing a sampling of the data so you know what's in the table column names and data formats without being "penalized" by doing a `select * from crew` initially to see the lay of the land. I do that when crafting real world queries all the time to get antiquated with it.
My broad aim was that people who want to learn could do story mode and the people who already know it can do the challenges. "Pudding" in particular is designed as a PITA test.
Yea maybe I add something that allows through simple select statements without incrementing that count. My reasoning was if everyone is getting penalised the same way is kind of fair and the autohint gives SOME idea of column names but you're right it's still necessary to look at the tables
