Hoi ILeftTheGame_,
Sorry to tell you that your map have been rejected.
The theme is not original, because the Nether theme is already used a lot. The build could be better, mostly outside the build ; it's not really attractive and pretty plain from the outside. The parkour could be better, I think it's pretty repetitive and pretty easy for an expert, even with the poor amount of checkpoints, but too long for a hard.
Thanks for submitting your map, would be really good to see more maps from you !
