Made an interactive Vim practice tool to retain commands – looking for feedback

Hey everyone, I’ve been learning Vim recently and struggling with retaining some of the motions and commands — I realized I needed a way to practice actively, not just read tutorials. So I built a little web-based trainer for myself with short lessons and interactive drills. It gives immediate feedback and lets you repeat commands until they stick. The idea is to make it feel like learning to type: small, repetitive practice sessions that build muscle memory over time. Would love any feedback — especially from others who struggled with Vim at the beginning. What helped you most? What would you add or change? (Free to try — I can drop the link in a comment if that’s allowed.)
