Here is my 2 cents
You spent all that time creating the icon weapons and being able to customize your uniform and such and honestly I was like cool this is going to be cool. then I got to the play and was really disappointed. As others said, it suck not being able to shoot someone at close range. Fix it so you can or make it so they can't go to a spot where you are firing....I mean simple as that.
Make your aiming cursor MORE visible. I can't tell you how many times I loss the cursor in the background. I like to know what it is I am aiming at. Lastly, slow down the progression...I mean from cave men with axes to catapults and a guy in full body armor in 8 seconds? How about sending waves progressing through the ages or something.
You spent so much time preparing the game, you really need now to spend some time working on the play-ability of the game to make it more fun. You shold get like a 6 or 7 rating with all the menu work, uniform changes and weapons and such...but your getting a 3 because I know if you can do all the other stuff, you have the knowledge and ability to make the game play better but you didn't. Make it better and I will be glad to give you the higher rating you deserve.
