very cool ~ I recently made a puzzle game, https://puzzles-game.com/, which is also adapted to different screens and adds numeric keyboard support, which is somewhat similar to what you mentioned in your blog

It's inspired by Simon Tatham's classic puzzle collection, nice!

A similar type of puzzle I made in the past: https://www.quaxio.com/sliding_puzzle/puzzle.html
