I have tried it on the deck. It just starts up as a black screen. I have tried it with different versions of proton as well.
I hope one day this game does get linux/deck support. I played a little bit of it in a windows cloud machine and really liked the first couple of hours. The deck is my preferred way of playing VNs so I was hoping to finish this next.
BTW, are you working on another game. I noticed this game is the only game you have published on steam and it came out about 4 years ago.
Maybe there's a way to compile a Linux port. I'll look into it.
I'll definitely make another game some day. I'm still not sure what kind of game it will be, but it would be a completely different art style.
Keizudo took me over 1000 hours to make, and I've only made a few hundred boxes of it. So unfortunately I can't quit my day job to work on a game full time.
I understand the struggle of balancing work with personal projects. I do hope you get another game released. I can probably just stream to the steam deck from a windows PC. If that works then maybe I can finish it in the next week or so. Thanks for atleast considering a linux port. I think this game would be a perfect fit for the deck so hopefully it works out.
