Though I like the concept, the game itself isn't stable for my Mac. It started lagging out in the Spider Web City, so I closed other programs and reopened the game only to find it somehow got even SLOWER. So I rebooted my computer, and tried again to see if I'd mucked something up before. It ran fine until I got to the city again. Then the entire thing. Just. Simply. Froze. Not just the program, but my entire computer to the point of needing a hard reset. I am sorry, but though I love how this game looks, and its concept, it is just too unstable.
