Ooh this looks interesting, thank you. Do you know if it teaches more high-level Vim concepts (like text objects), or just the basic commands like hjkl?
I only briefly played w vim adventures ages ago after I already learned vim and liked it but don't remember how far it goes and am not the OP but:
I wouldn't underestimate how good it is to just get those basic moves and simple commands in muscle memory... frees up your attn to get curious about "I wonder if vim can do X" and then self-study is a breeze
Usually comparisons are biased as it's not easy to get over you own point of view. I personally don't like hooks and find them ugly and convoluted. But there is a good reason for React to be as popular as it is - also connected to many successful products.
