last night i was playing on minecraft singleplayer messing with stick pistons when i had a idea, i thought it would make parkour alot harder if using sticky pistons you could have the blocks you have to go to was constintly going into the wall and back including the ones your standing on. i tried building it but had alot of trouble since iv never built anything like it. i look around the internet but didnt see any parkour similiar to my idea. I am looking for someone to help me build the piston parkour. if you are interested please commet saying that you are interested
