I hardly remember any if the nore specific details of the game, all I remember is that it was stickman based, it was a flash game, it had a black, white, and red (quite blood) theme, it had a storyline and a sequel, it had a lot of guns, there were multiple characters with you (the main character), and I beleive they just did a bank heist? I'm not too sure on that last part.
There are so many of these that it's basically impossible to pinpoint a single one. On a side note, I remember playing these a bunch when I was a kid, the only one I can really remember is Electricman. Those and the papa's games on CoolMath. Good times good times.
