So for those who have watched the trailer but have yet to check out the game. It seems like it is worth trying out. I have just watched one gameplay on youtube and it seems like a good game.
Check out the gameplay.
I want to say it's one to one, but in all honesty I'm a bit fuzzy there. I can recommend JoyFreak's sister site AdminIntel - Admin & Webmaster Resource where there are lots for people of varying degrees of expertise with development, you likely can get a far more precise answer there!
