Very short little game.
6 levels, then a "find the hidden object"
6 levels with a new twist, then another "find"
6 levels with a new twist and another find.
Then it's done.

But then you unlock the extra puzzles.
Music is chill, game is easy, worth getting during sale or in a bundle for less.
Can be completed in under half an hour, or 1 hour if you also do the extra puzzles and achievements.
