I used /spawn and to be honest, I did kind of use the block glitch thing for the redstone part, but by using the pistons and timing. (I don't think you can block glitch the common way on the parkour. Then again, I've never tried anywhere, but on the outside, because I wanted back in.) My main problem with the parkour is parts of it are made for two people, which is unfair, especially on the last one. (like how often are you really going to have someone there to help you, let alone is willing to?)
