Nice implementation and animations.

I've used summle.net for a couple of months.

Few ideas from their implementation: - achievements, badges and stats - hints when your stuck - 3 levels (for kids, normal, extreme) - quick erase all - % of overall resolution from other user - best solution (in N moves VS your K moves)

Few other ideas: - dark mode - practice mode (more user retention, just like quordle)

Enjoy your code and your project, I'll try to add it to my daily puzzles.
