Hello ki0_
Unfortunately, I will be Rejecting your map.
The theme is original, but the build isn't great. It is quite plain and blocky. I understand it's inevitable as calculators are flat, but try to use a bit more colour and detail in the build where possible.
The parkour is quite repetitive. You had a few different jump styles which is good, but it would be great if you could mix up the jumps a bit more, as well as experimenting with different blocks and items when building the parkour.
The length is good for an easy/medium map, and the parkour is good for an easy map, with a few jumps being too difficult for an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
