This game is too relaxing, its like a very calm chilled game ninjas do when they are trying to relax while staying very focused. The minimalist style was very nicely pulled off and it looked very good, the slow sway of the camera gave life to the scene without over doing it and the music became a lullaby for me. I played for a good 3 minutes. F1 however opened a new tab of information when pressed. I would love to see more feedback when clicking the ninjas though as sometimes i felt I was miss clicking them.. maybe a ching! or dong! when right or wrongly placing ninjas to their respective doors! :) Keep up the great work!
