The download says there should be a Linux and Mac version it it as well, but only provides a Windows binary. This won't work, there won't magically appear Linux or Mac versions just because you ticked that icon in the Itch page - you will have to add the Linux and Mac target modules to your Unity installation and switch to them and do another build!
Interesting mechanics though I didn't really get how the rolls were supposed to work (I guess each one of the buttons corresponds to pitch, yaw, and roll).
More importantly I quite didn't get if or when I hit one of those turrets. I could only make out I felt I was losing (all lives depleted and going low on the last one's energy) and suddenly there was a "You've won the game" message...
