NINJA UPDATE: It seems most issues are fixed, but for reasons i don't fully understand - please go to Creatura properties and select "Verify Integrity of Game Files", or else textures can glitch out.
NINJA EDIT: Hey folks, i'm aware of the wall of crashes on startup, in the upcoming hours please expect revisions to fix that terrible mess. Sorry to everyone affected!
With update 0.6, Creatura has been ported to Linux and SteamOS systems, without missing any features from Windows version.
If possible in future, the default renderer for Creatura under Linux will be Vulkan, however right now Creatura starts in OpenGL mode. Vulcan mode can be forced as command line argument, if your GPU supports it.
In case of any issues, feel free to report them on our official Discord channel, and any discovered platform specific crashes should get resolved in upcoming updates.
