I've released a linux and mac build for the game... but unfortunately it isn't tested in any way nor can I personally test it myself. All I did to build for those platforms / operating systems is installing the required modules for my unity engine and choosing to target the game build for those platforms in the editor... so I don't even know if it's going to be functional or not...

Until then I could only know if it works / how well it works from other people... I'd highly appreciate any feedback from linux / mac users just to know if the game works! 

Sadly, if these build don't work as intended / the same way as it does in windows... then I'm probably going to just keep the game released for windows until I can save enough money to get more storage to dual boot into a linux distro for testing a linux build...
