We initially wanted to do a Linux version, but there were actually a bunch of issues that popped up when we were doing the testing phase. Due to the amount of time needed to troubleshoot and fix it compared to the number of Linux users I've had on past projects, we decided it was better for us not to do a Linux build for this project.
No worries! This game seems a lot more involved than the standard "click to read the comic" VNs and that, I feel, really shows some of the dissonance in the supported default libraries. A whole bunch of "Just because it builds, doesn't mean it will work properly/good."
And I'd much rather have the "the testing showed it was ass so we scrapped it" than the "here's the build... what do you mean you can't see the CG's because it crashes when you click on the mcguffin!?"
