Hoi Jackiee_,
Sorry to tell you that your map have been rejected.
The theme is pretty original, even if there is already a "Clouds" map, adding thunder is interesting. The build is average, look nice, but all those glass pane can makes people lag, and most of your parkour is floating around the build, making your map messy. The parkour could be better. it's a bit varied, but it's a bit repetitive and boring, mostly because we climb a lot in your map.
However like I said before, the theme is interesting, and the build is nice.
Thanks for submitting your map, would be really good to see more maps from you !
