Score: 5.7/10 (Innovation: 5, Technical: 6, Documentation: 4, Utility: 6)

hjkl is a browser-based interactive game for practicing Vim commands through guided and prompted text edits. It covers a wide range of Vim skills—from basic navigation to text objects, marks, and counts—without requiring accounts or storing data. The project stands out by offering a structured, hands-on learning path for a notoriously steep tool.

Target audience: developers, particularly backend and devops engineers looking to improve terminal editing efficiency
