I have some major issues with this game
1)The people look too similar. The men all look the same, the women look all the same, and the children look all the same.
2)You can only kill lots of people when they overlap. You should have a button that lets you reveal the bomb, but not blow it up to scare the people and herd them into one spot. But you could also have a thing like once you do that, you only have limited time before the cops come and sniper you to death.
3)No ambient sound. You should get a sound for running and maybe a few bird calls in the background.
Other than that, cool game!
