This game is slow and even on the easy setting is almost impossible to play. Not worth any money at all, much less 4.99.

I played the retail edition of this game and didn't have any performance problems using my NVIDIA 9400.

On my mid 09 mbp 9400m 2.53ghz, it just barely meets minimum requirements. I purchased this at the app store 2 weeks ago and, I was able to complete the whole game without any bugs or crashes, but the frame rate is atrocious and the gameplay mechanics are ambiguous. The first 5 levels were exhilarating and I got the gist of what the gameplay would be like,( stealth, espionage) but they switch up mechanics by the end, and the genre turns from stealth action to 3rd person run and gun. Its no wonder this game was on sale for 3 dollars because thats all it's really worth. Great idea and concept but terrible execution in the long run. I suggest anyone with a mid to low mbp, like mine, to just avoid this pitfall, and Digital Tribe LLC should raise the requirements bc its very misleading, or at least release an update for the nvidia drivers bc this could have been ported better.
