People that grew up reading mad magazine as kids will enjoy the retro mode and the overall look of the game however the gameplay mechanics fall short and Im left with regret for having bought this game. It might sound bad but I want my $0.99 (CAD) back. The tutorial should be an option (suggestion) that pops up at the start of the game instead of being forced on the user. The fact that you need a dozen screens to explain how the game is played (I didnt count however that was my feeling) should tell you that your gameplay mechanics dont work. Use the gestures inherit to the iOS platform like pinching, pulling, double tapping and multi touch instead of placing menus on the side of the screen. You can do better than forcing the user to move back and forth between game screen and menu all the time. It makes the whole experience irritating.
A few suggestions to improve gameplay:
1) forget the d-pad style movement, instead a single tap should move the spy to that location;
2) double tap should be used for interaction with the game world (contextual action button);
3) a pull should be used to open the spys inventory/weapons menu;
4) a pinch to close said inventory/weapon menu;
5) introduce a turn based strategy mode to introduce users to all the concepts needed for gameplay.
