It has been quite some time since the full release of the game, but thankfully, the game will be released for the Nintendo Switch, and I have been working on it.
In addition, I have added simplified Chinese as the first step of localization that I have been working on at the same time.
It is difficult to add more languages because it costs a lot of money, but as sales of the game increase, I would like to gradually add more languages.

I am very grateful for the positive feedback I have received from people who have played the game, and I hope that something will lead to more people playing the game, and that I will be able to localize the game and create a sequel. If you like the game, we would appreciate it if you could write a review on Steam or tweet about it on social networking sites!
