Hello SKaR66,
I regret to inform you that your map is being rejected. The theme isn't very original, since there is already an Airplane map, or maps that have planes in them. The build is okay, it is accurate to the theme, so good job on that!
The parkour is the main problem with this map. It's very confusing, I really couldn't figure out where to go as there isn't a clear start. Two jumps I perceived to be the correct way were too difficult for a hard map, and one way I found wasn't even the right way to go as the signs were all flipped backwards compared to the proper path. The path is just very strange overall. The path I took was far less jumps than the average amount for a medium.
The parkour was varied, but it was pretty much all floating which didn't help me directionally, and makes the build look messy. Try to attach the majority of your parkour to the build in some way. You can see recent examples of this at /warp beta on the server, or in the Accepted maps subforum. Additionally, the inside of the plane is exploitable, as you don't have to do any of the parkour to finish the map. Behind the pad is a pretty easy jump to get onto the pad.
Thank you for submitting this map! If you have any further questions, feel free to message me here on the forums, in-game, or on Discord.
