Ooedo Blacksmith (Japanese)

Is a fun little game. Knowledge of Japanese is strongly recommended if you wish to follow the story dialogue or to know what to make for the special orders. However to just play the game, it can be figured out with just a little trial and error, as the combat is pretty simple and the little mini-games are simple. If you have ever played a rubbing/touch game you will know what to do. And the blacksmith enhancement is basically a simple rhythm game. And while it is made by the same developers as the Criminal Girls games, it is not nearly as risque, so if that is what you are looking for, just know this is more tame by comparison.

Some understanding of the native language is needed. But overall a nice diversion if you have nothing else on your plate.
