Incredibly creative concept - a cool mash-up of a "Papers, Please" type management sim and a turn-based strategy game. Might benefit from some more info/feedback on how best to use the defensive elements (perhaps some range highlighting on the grid for elements like turrets). Also, it could be interesting to add more synergy between the two gameplay mechanics (for example, if the way the player answered emails affected the type/amount of defensive resources you could deploy). Regardless, I love the idea of having the dual systems, and the theming is hilarious/very unique. Hope you keep fleshing it out!
