Hello frsz and XpEmerald!
I am here to give you my review of the map. Please remember that I am not a Map Judge and my opinion does not affect whether the map gets accepted or rejected. If the Map Judges disagree with what I say, they will go by their own thoughts!
Firstly the THEME of your map. I would sadly consider the theme to be a little unoriginal, since there are multiple lab related maps already (examples ManaLabs, HawkinsLab, TestFacility, Lab) but I'm not sure if a lab desk has been done before! If it is, then I believe the theme is fine!
Secondly the BUILD of your map. I think it's pretty good! It looks like a desk and has some usual lab tools on it. I also love the detail with the open shelf, well done!
Lastly the PARKOUR of your map. It was okay, I thought it was alright, not too special but it wasn't bad either. The checkpoint placement is good, the parkour block choices were great and the parkour was great length wise! The main problem is how difficult it is. It is WAY TOO HARD for a Hard map. I would recommend you to go through the parkour all over again, and nerfing every single part because right now it is way too difficult and more fitting for a Medium Expert map.
Again remember that my opinion is not always correct! If the Map Judges disagree with me, they will go by what they think!
Right now, it's a -0.5 from me :) Good luck!
