Of course, I will test your game on Linux! And you can add me in Steam if you don’t want to drop the link to the test build here.
I actually figured out a strategy for your game too. I just always stay in the center of the bright and dim light that I drop below my feet and discard the dark light by throwing it at the edge of the screen. It’s the only way to be always aware of the invisible ghosts and you can already see other ghosts before they enter the circle.
Still, even with this strategy your game is difficult, since it’s hard to hit the ghosts at such short distance. And I need to time discarding right or the ghosts will get me. :-D
Thank you for playing my game! I replied to your comment there too.
