Your map is in reviewing.
The theme is original, and the build is good enough.
The parkour is the main concern. Overall, the flow feels clunky and there are quite a few jumps that don't fit the difficulty. Examples will be below.
Jump is too tricky (could change the bottom pane to glass block.)
The first jump here is too difficult, and overall this area doesn't flow well. (could either remove timing or improve the flow.)
Nerf needed here.
Nerf ladder->glass pane jump here.
Checkpoints here could be rebalanced- at least 1 by the timing area and one beforehand.
You have until one month from now (August 22nd) to make these changes; if I have not been contacted about changes by this time, your map will automatically be rejected.
