Hey Berrgurt,
I'm sorry to have to tell you that your map has been REJECTED. Although we do have multiple "Space" themed maps, we have no "Astronaut" themed map. Therefore, I think the theme is original and creative. But, the build and parkour are not good at all. The astronaut (that lacks proper shaping as it's just a statue) and the floating parkour both greatly hinder the attractiveness of the build. The PK was way too easy for a hard, even if the length fit the difficulty. The difficulty would spike at times as well, make sure to have an evenly hard map when making a hard map. That isn't the only issue with the PK, it was also very repetitive and primarily floating. You have to use a variety of jumps/blocks when creating parkour because if not it will feel incredibly boring. There were multiple single glass or glass pane segments. And, try to incorporate your parkour to the build. Don't have it all just be floating. I hope you take these criticisms into consideration when building future maps, good luck!
