itch.io

Just a question, when I downloaded the zip file on my mac I followed all the instructions on how to open the game, but for some reason, when I click on it, it doesn't open. Even if I control click and press "open" the game still won't open on my mac. I've also tried redownloading it but it still won't work. Please tell me what I may be doing wrong since I really want to play this game.
