Picme is the classic mix of a puzzle game and a visual novel, taking the relaxing and challenging nonograms (a.k.a picross) puzzles and giving the player a motivation by unfolding stories of sexy women.
You play as a man that, after dying unexpectedly, wakes up as a ghost, only to find out he will still need to work on the afterlife. Fortunately his boss is a fairy named Leaf, that guides him on how to help people find lost stuff. Together you're helping out five women to find their true desires, while corrupting them on the process.
Nonograms are the perfect blend between minesweeper, sudoku (although not as hard) and pixel art, where you mark pixels on a matrix based on logical clues, creating a pixel image in the end. This game does offer a full explanation and tutorial on how they work, and you'll naturally begin doing easier puzzles before you can tackle more complex ones.
