I decided to play them in order. Got bored with #1 and moved on to #2, easy. Now I'm on #3 and doing some training. Somehow I managed to click away from the screen and when I came back to it my guy was still shooting. I've left it going while browsing other sites (thanks for tabbed browsing, Firefox!) and my high score is way up. I just wish I could shut off the music.STICKMAN SAM 4: Fantastically Good Flash Platform Game
Still haven't played #4 yet, though.
EDIT: I got tired of the music, so I shut it off, but not before taking a screenshot of the year. (and about 3/4 of the way to the next!)STICKMAN SAM 4: Fantastically Good Flash Platform Game
