This is a cute game. I like the way you made Hitman meets Where's Waldo. The chaotic scene is fun to parse through visually.
I had trouble with the viewport, but then in full screen the game is only in the top left. Also, after playing tutorial or a level, a page refresh was required to click buttons on the title screen.
I can totally sympathize with having to beg people to play your tutorial...we are having the exact same issue where people are saying they don't understand or the game is too hard.
Good job overall!
