Hello OhDuckie_,
I regret to inform you that your map is being rejected.
The theme is original. however, if you are going to represent certain countries, it would be better to stay away from flags as a main focus. As mentioned above, your main build is pixel art which is no longer accepted on the server. Try to focus on maybe some landmarks or other ways to represent certain countries that would allow for a more detailed build (NorwegianDelicacies is a good newer example of this!)
The parkour has some variety throughout, so well done there. Overall it does feel a bit messy though, but this does have to do with your build as well.
Thank you for submitting this map, I would love to see more submissions from you!
