Hello, I went ahead and made the linux download available again. If you would like to test the game and see if it runs for you that would be great. Honestly not too large of a concern for us anymore, but if we were to find out it works then we would add a linux build to Steam as well as publicizing the build here. (I'm not sure if the linux build actually matches the most recent Windows/macOS versions..)
EDIT: If you would be open to trying the current build and maybe an additional build if it crashes after the splash screen, feel free to contact me from my websites contact form here https://tallenstudiosdev.com/contact-us.
