I have two feature requests.
First, it'd be helpful to have the download file marked within Itch as containing a Windows executable. This lets users of the Itch Desktop client download and play the game from the client itself rather than using a traditional web browser to download the game.
Second, a download for a Linux build (ideally, marked within Itch as such as described above) would also be appreciated. It's possible to run the Windows binary for this game in Linux using Wine (though using winetricks to install cjkfonts in the wineprefix seems to be necessary for this game), but a Linux build would make this game accessible to less technical Linux users. (Similarly, a Mac build would benefit Mac users as well.)
