Idea
I like what you wanted to do, and it makes the most sense to do it with a Parkour game. But as other's have said, the pausing of the action to actually do the action, isn't too appealing. In parkour you normally see your obstacle coming up, and so you prepare for it, and do it. Why not have the same idea with the game? You see your click, drag, or roll-over coming, and you do it. No pausing of the action, fast paced but not too fast, and still challenging.
