Hello fribe, joeyism, andrea_44,
I regret to inform you that your map is REJECTED.
The THEME of your map is original, we do have other science maps but nothing based on the periodic table. So good job on that!
The BUILD of your map is a problem. While the map is accurate to the periodic table, it is very plain making it hard to designate it as the table at first glance. I recommend adding more details for each of the elements as well as adding block texture.
The PARKOUR fits the length an expert map, so good job on that! The difficulty fits better under a medium/hard map. You have added variance to you map, but most jumps feel like the blocks are added just for the sake of variance. This causes the map to not be as enjoyable and limits the flow.
Thank you for taking the time to create a map, I hope to see more submissions from you in the future.
If you have any questions feel free to reach out to me on discord at Elly#3703
