http://dan-ball.jp/en/javagame/ranger/Stick Ranger (often abbreviated to SR) is an action RPG Java game created by programmers hired by ha55ii. It was released as V1.0 (ALPHA) on July 18th, 2008. The official description of this game is given as "Four stickman of adventure!". In the game, the player controls four characters with the mouse, dragging them in a similar fashion as in Irritation Stickman, but without the timer on holding the character. These characters wander about, defeating enemies they encounter and passing through levels to reach bosses. The levels are all optional (the player can simply drag a character to the next sign to skip levels), but to unlock the following stage the player has to kill the boss at the end of each stage. For a long time the final goal of the game was to kill the Castle Boss located in the Castle. With the addition of stages after the Castle, the final stage is currently shifting to different stages. Even after this final stage has been accomplished, the player can still continue playing to improve their characters and collect more weapons and items.

Pretty easy, but I find it to be a nice time killer.
