You appeared in some kind of room. It had gray walls, a stone floor... behind you there was a exit door, and on the side there were something like windows from which light came. When you appeared, you immediately heard a voice coming from somewhere above: "Hello!Im Parkour Bot!Welcome to my Parkour course." Voice sounded good and nice,like he didn't want to hurt you or something like that.Before you was two platforms and abyss under them.So..thats the parkour..look easy.Just jump..
