Hello iamboogie & ethanjlong,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are multiple maps with a similar theme, as well as an iPhone themed map already (
iPhone - Insane) I would recommend referring to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build isn't great, as it's mainly just a pixel art. Try to create a build that has more shape and depth, as well as a bit more detail. You can have pixel art as a decoration in your map, but not as the main build.
The parkour is very repetitive, as it is mainly normal blocks and ladders. Try to experiment with a larger variety of blocks and items when building jumps, this will make your map overall more enjoyable to complete.
Most of the parkour is floating. Try to avoid having jumps floating over the void and incorporate it into the build more where possible, as having an excessive number of floating jumps can make your map look quite messy.
The difficulty is good for an easy map, but the length is a bit long. Please read over this thread -
https://manacube.com/threads/must-read-map-submission-information-format.649/ to make sure your map fits within the requirements.
Thanks for submitting your map! I hope to see more maps from you in the future.
