There should be modes like endless mode, story mode, or just levels. You can also add a map creater that the player can create for him/her or others to play. That can open a lot of other opportunities like an online gameplay. If you ever made a story mode out of this game, I have a few ideas. There would be a bunch of other Stickman Hook at the left side of the screen chasing the original stickman and the originals stickman are trying to run away.
