Where's Waldo?
It has a similar concept to Where's Waldo, but with guns :P
ART: Basic, however it was fine since I would almost call it a style in this case.
Gameplay: It is easy to grasp and understand.
Story: Lacking but this is a demo so I will let you off on that.
HUD (Heads Up Display): It was confusing to me, there was stuff that didn't need to be there like the thing in the bottom left corner. I guess it is to serve as a place for some little Easter eggs but it is a distraction from the game.
As well there is no point in me knowing the coordinates of my cross hairs, I guess this is for debugging? But w/e there is no need for us to see it unless you are going to include it in future levels somehow.
Difficulty: Was set to a default easy, cant say much about that. i guess the higher difficulty levels would have more targets, less time, targets moving in random directions?
OVERALL:
Not bad :)
