There is the vim adventures site https://vim-adventures.com/ but it doesn’t sound quite like what you are looking for.
Are you implying there is an easy way to learn Vim? :)
I remember the "Learn Python the Hard Way" web-site, but I'm having trouble even finding that. It looks like there is a book and a course instead. I wonder if the web-site version of these courses were eventually phased out?
This might be a good alternative:
Unrelated to Vim but reminds me of https://yannesposito.com/Scratch/en/blog/Haskell-the-Hard-Wa...
Everyone’s throwing in a vim learning resource so I suppose I’ll join in with this: Learn Vim the Smart Way - https://learnvim.irian.to/
https://learncodethehardway.org
I don't know if there was a vim book. There's a Unix book.
google can't seem to find it but it did find this which seems up your alley:
You may be looking for "Learn Vim Progressively" by Yann Esposito. It's also how I got into Vim almost 10 years ago.
