A hard fighting sidescroller. Fight as a ninja and pirate as you progress. One stab and you’re dead!
Back then flash didn’t have any physics libraries. Sure, Box2D came along at some point, but even that wasn’t easy to get into. Usually, you would end up writing physics yourself. One simple solution is to use constraint physics – a bunch of points that try to stay within a certain distance from each other.
So this game was built to use it in a game. Admittedly, it didn’t add anything to the game.
