Hi,
Trying starting this game (via terminal) on a Linux system I get an error message:
"./Fractal-Collector-Linux.x86_64: error while loading shared libraries: UnityPlayer.so: cannot open shared object file: No such file or directory"
And in fact there is no UnityPlayer.so Linux library next to the main game executable, so please take a look at your last published Linux version .zip file.
Thanks anyway for your game.
