Hello khirina!
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 matter whether the map gets accepted or not. That being said, if the Map Judges disagree with me, they will go by their thoughts!
Firstly the THEME of your map. As there is no map of a flower dome on the server yet, and the only somewhat similar looking map "Terrarium" was rejected, this is an original map submission in my eyes! Good work!
Secondly the BUILD of your map. It is absolutely incredible. The map is beautiful, and truly eye catching in my opinion. It is also accurate to a flower dome, there's nothing I dislike in the build. Great work!
Lastly the PARKOUR of your map. I found it very enjoyable to play. You had nice jump variation in your map, which made it interesting at all times. I also love how it was more technical rather than just using random blocks. The map length is alright for an Insane, even if it is on the shorter side, and the map has a good amount of checkpoints. While I don't personally think the map is too difficult, I think it does not fit Manacube. It is too technical and has very difficult jumps and parts to it, similarly to Surv's Minesweeper. I don't see the map being accepted without nerfs, but I'm wishing for the best!
There's also a rather huge shortcut in the start, you can jump on the barriers from one spot and skip past the 2nd teleport.
From me, a +1 :) Good luck!
