yes its easy, and the game seems ok (visual + sound) up to the main menu,
all unity3d games play almost effortless in linux
out of curiosity and for experimentation.. in windows what do you need? opengl? directX? which vertion
do you have some unity plugin for mouse that is incompatible with linux perhaps?
I don't use any specific mouse controller beyond what is by default on unity.
by default, Unity tries to run the game on DirectX. My project is built on DirectX11. I'm not really sure what unity does depending on the user system, really. I know you can force the game to run in opengl with a command line. But on Linux, I can't know.
I read something about the mouse showing in windowed mode instead of fullscreen. The game possibly starts in windowed mode, right?.
I cannot be of much help today, I'm trying to finish a release that is already delayed.... So have fun researching yourself I guess v_v
