Hoi rmc22,
Sorry to tell you that your map have been rejected.
The theme is not good, yeah there is no "Daylight sensor" map, but Minecraft themed maps are overused, and not original. The build is not good too, the daylight sensor looks decent (a bit plain ?), almost like the real block, but it's the problem, they look copy/pasted from the real Minecraft block (It's like a pixel art you see ? That another reason why I hate Minecraft themed maps.), the parkour is decent, it's varied but like Noah said, it's a bit repetitive. I'm not gonna talk about the difficulty, because I agree again with Noah, it's too hard for an expert (The checkpoint placement is important too, that why I think people said your map is good (?) for an expert (even if I still think it's a hard expert with more checkpoints)) but could fit the insane difficulty.
Thanks for submitting your map, would be really good to see more maps from you !
