Thanks for playing ! Saw the video, I cringed at some terrible language faults ("hitted" ? Seriously me ?) in the game's text, whoopsie doopsie...
Well, for the system, I'm not really sure : for our test, we nearly all had very correct laptops, with intel core i5, and nvidia GTX graphic cards (never tested the game on another composition than intel proc-nvidia gc) . Personnally, with a GTX950M, it runs smoothly. On a classic iMac, it went well too, with max graphs. It's not near well optimized, so in theory in Medium or Low it could run on a toaster, but again it's no certitude.
