Hoi Bunstop,
Sorry to tell you that your map have been rejected.
The theme is not really original, since the "theme" as been used twice (Portal (Donator) and Lab (Dropper), they are still quite different tho (The Companion Cube is on Portal tho)), so be careful next time ! The build is not really good, it's plain and not really attractive in my opinion (It's hard to do better with this theme so I can understand you can't improve the build), and the parkour is decent, it's varied and "fun", probably just not an expert but more like an insane (Remind me a bit of Zaphkiel, short map with almost no Checkpoints, and there is also 2/3 jumps that are just not expert difficulty (around the first cp)
Thanks for submitting your map, would be really good to see more maps from you !
