This does cost money, but if you are serious about learning vim, this is an excellent game, and reasonably priced. One benefit I found is that the game creates a curriculum that exposes you to things you wouldn't otherwise try in your day to day, simply because you don't know them.
It helped improve my vim muscle memory substantially. Well done imo.
It's reasonably priced if you consider it both a game and a learning resource. If you already know vim fluently and just want it as a clever puzzle game, $25 is a reasonable purchase price but steep for a 6 month license. I have bounced off it several times over the years, after initially clicking the card icon intending to pay.
