Huh. The windows version doesn't have a .pck file, but works fine anyway. Is there a way to make Godot (I assume you made this in Godot) export the games as a single file? Anyway, the game is fun. I don't know why I never thought of using face masks when I was trying to come up with a game idea. But shooting face masks at poisonous cloud breathing zombies is very topical. Good job.
