Hi! I'm so sorry that it isn't working for you! I have noticed a lot of Mac players having issues opening it, I'll see what I can do to find a solution! I think that it might only work on windows though, I'll double check. I made the initial demo using Pixel Game Maker MV, and am currently in the process of moving everything to Unity and will update it here and that should also resolve those issues, and make the game run smoother and I'm adding lighting effects so stay tuned!
