I like the style of river city ransom, so I made it in that vein a long while back. It is a similar style, but a different character - could I get sued for using a style? If so, it can be easily changed.
I was working on another character that fits the game more anyway.
That sprite started out as a joke. I was going to make fun of Metal Gear in a small game, but when I used him here I liked the character enough to leave him in.
