Apparently, there's a problem with launching the game on Windows 7, what I'm running, and they're working on fixing it.
Actually, I was sent a file for the fixed version a few hours ago, and was asked to test it. I don't consider myself very efficient with computers, and I figured I might get a quicker answer if I asked how to launch the file on here. I've already extracted from the folder, but I'm not sure what what to do from then on.
Finding one shouldn't be too difficult, you'd be surprised how many of us are still out there :) Not too many games won't run on Win7, including Unity-based games as a matter of fact... But I understand it may be something with their engine and a problem to fix. Perhaps you should contact them and call them racists. I appreciate the effort but honestly still doubt that you'll have it fixed. Be the hero and prove me wrong :P
Edit: I didn't see Whale's reply, maybe there is still hope hehe
