I'll be giving this a +1. The theme is original. The build is really well done, I'm actually quite impressed with this. Like Chloe said, it's clear that a lot of effort was put into this. The parkour is definitely challenging enough for a hard, and the jumps are well-varied.
I'm going to give your map a +1 The theme is original and the build is really well done. I really like the variety in the jumps, and as far as difficulty and length go, I think it fits the hard difficulty well!
Happy to tell you that your map have been accepted !
The theme is original (There is already one Doctor Who map (TheTardis), but it's really different compared to your map). The build is also good, it's attractive and well made. And the parkour could be better, I think it's quite repetitive, mostly at the start. I've also changed some Checkpoints placement, because some checkpoints were way too far when some other were too close.
Thanks for submitting your map, would be really good to see more maps from you !
