its bit Toooo hard, too many of those "Jump around the Wall" jumps. for a first map its not bad but there's lot of room for improvement as i wasn't able to MLG because i cant place water in adventure mode so i had to switch to survival and also had to do /kill to reset... maybe try covering the ground with lava. nice job with the command blocks. the last thing i want to say was that the part with the shulker boxes was my favorite as i've never seen that be done in a parkour map before... kudos for that. i look forward to future Parkour maps!
