Hoi AnnieoL,
Sorry to tell you that your map have been rejected.
The theme is pretty original, since there is no maps with a similar theme. The build is pretty good too, but maybe a bit messy, because there is some floating jumps. The parkour is why I reject your map, it's really repetitive, and too short for a medium in my opinion, please try to use more blocks for your parkour, like iron bars, ice, soul sand, trapdoors…, also please avoid using too much invisible blocks, try to replace them with glass, or use signs.
You can resubmit your map if you want, if you patch the parkour, I will be happy to accept your map !
Thanks for submitting your map, would be really good to see more maps from you
