• A real difficulty curve: puzzles that once took two moves now take six by level 50, and climb to twenty. • Empty lanes are easier to see in dark mode. • A new launch screen: every Luys game opens on its own colour with the Luys mark. • The win panel no longer closes when you tap beside it — use its close button. A panel that appeared mid-drag could throw the level away. • The version number is shown in About.
