Sorry for the inconvenience. A Linux version is possible but not currently planned during our early access phase.
We use some assets that we are not sure will work outside of Windows and can therefore not easily convert to Linux.
In the future, we would like to expand to more platforms, which would mean it would probably be easier to make a Linux port after that.
We would like to take a look at your specific problem. Is it possible for you to DM us on our Facebook, Twitter or Discord?
