itch.io

so does it not work? The pck file should be embedded.

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.
