One of my favorite game genres are puzzle games, it helps if they are really creative with an interesting story to boot. When I saw this in he App Store and read it's description, I decided to check it out.
Style wise this reminds me of Monument Valley what with its soothing music and the fact you play as a mysterious girl surrounded by buildings in the middle of nowhere.
However instead of perspective puzzle solving you have to ring a group of three to four bells in a specific order which either move automatically, need to be moved manually, or require you to move your character to a specifics space to get the order right. That in and of itself can be more challenging then turning and flipping buildings around (though I would still recommend Monument Valley).
On the whole this a really unique and challenging puzzle game with an interesting story and I can't wait to beat it.
