Hello Jaxomlotus and ErraticMC,
I regret to inform you that your map is being rejected.
The theme is original, as we don't have any specific "Roman Colosseum" maps, so good job on that!
The build is somewhat accurate to how the build would look in real life; however, there isn't a lot of block variety used, which makes this seem plain. Try incorporating more blocks/decorations into your build!
The parkour is quite repetitive with straightforward jumps, ice and ladders. Try to incorporate different jump styles throughout your entire map! You can look at recently accepted maps for some examples of these! The difficulty of the jumps is good for the easy difficulty; however, 83 jumps is way too long. For the easy difficulty, it's ideal to have around 20-40 jumps!
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
