Hey there, before going ahead with your map submission review I'd like to inform you that I'm only giving you my personal opinion/feedback on your parkour map submission and my personal feedback will certainly not affect your parkour map submission in the slightest, I recommend that you take in my feedback to improve your submission if there are any flaws, you don't need to and you're free to ignore me but anyhow, before going ahead I'd like to mention that I'm a Moderator not a Map Judge so this is just my personal opinion and I am not accepting or denying your parkour map as this is only my personal opinion.
Parkour theme/detail: By far I don't believe that we have any themes that are considered 'paper planes' we've got some plane parkour maps but other than that I don't think we have any. For your parkour detail, you did an easy job considering the theme isn't overly detailed but it still needs some spicing up in my opinion.
Parkour difficulty/variety: For your parkour difficulty I would say that it certainly does match the difficulty of an EASY parkour map submission, you did a great job on your parkour variety, certainly felt quite unique and interesting at times and I didn't get bored playing your parkour map, good luck!
