Indeed… This game has been one of the; if not the only HQ adult themed game on itch.io with a native Linux build that I am yet to purchase..
As I do not want to get burned, and later come to find that support for my favoured OS, Linux; has been dropped entirely.
But if there is a problem in allocating time to test other OS builds, I can volunteer my time and effort for testing Linux builds. Plus, it wouldn't be my first foray into bug-hunting, as my brother is a game dev in the indie field. And judging from the fact that he keeps putting me up to it, I must not be that bad at finding bugs, then finding ways to reproduce the problem.
But not matter the way you in Momoiro Software decide to go about it, I do hope to find the continued support for Linux on your game's OS roster. (And I suppose for Macs as well, for that guy's sake.. If there is time.)
