More points for harder puzzles

The scoring has been tweaked in version 1.22.0 so that more points are awarded for solving harder puzzles. This version has gone live in the App Store today (Happy New Year!).

For Random Play players wanting to climb the leaderboard, this change makes it more worthwhile to take on the challenge of a higher play mode or puzzles of a larger size. But don't worry, none of the puzzles score less than before, so points can still be earned just as quickly with the smaller and easier puzzles.

Other changes in this version:

• Random Play reports the size of the puzzle being generated.
• Improvements to the contrast ratio of some puzzle elements.
• The screenshots used in the introduction have been updated and are now high resolution.
• Fixes to the info overlay and pencil mode settings for when dark mode is in operation.
