Great free puzzler that’s about the right level of difficulty for a casual game. The ads weren’t at all intrusive. Only one minor annoyance and an observation. Unlike most room escape games that let you examine an inventory item by double clicking on it, here you have to point and drag it up. One puzzle took a while to solve until I discovered this. This is also a game that wasn’t necessarily developed with a Western audience in mind. Several Japanese-specific objects are rather cryptic in function (Is that a hammer, a cane, or a plow?).
