It's hard to say without knowing exactly what error message you're getting, but I don't think low requirements would cause it to not work entirely. All I can say is that the Mac build provided has usually required some fiddling and I'm afraid I can't support it in detail.
Thank you for the response! I've been working on it sense, but have yet to succeed. I've decided to just play the game for free on NewGrounds, but wanted to ask if you could still send the gallery images or something since I can't access the game from the downloaded files directly. I'm not sure if I'm just tech inept right now, but I would really appreciate being able to enjoy some semblance of the paid game, if possible?
