Hey hey! Thanks for checking out the game, and I'm sorry to hear you're having trouble with opening the mac version >.< I don't personally own a mac, so I have no way of testing on my mac myself, and no idea how they work :( Someone else mentioned having the same problem, they managed to get it to run in the end, but they said they couldn't remember how. I'll have to ask in the support section for the engine I'm using and see if anyone there can help! I'll let you know as soon as I find out any suggestions :3
