Hello NMCAMANY & Conor2301,
Unfortunately, I will be
Rejecting your map.
The theme is somewhat original, there are a few maps based on shelves with various items already, however, none exactly like this.
The build is nice, it is simple yet effective, and has many nice elements to it which is good.
The parkour is quite repetitive, as you used a lot of ladders and normal blocks, in the future, try to use different blocks and items, as well as experimenting with the way you utilise these, to create more original and enjoyable jumps.
I found the parkour to be a bit confusing at times, and you did use a lot of barriers which made it feel a bit messy and confusing. I would recommend trying to cut down on the number of jumps a bit, so you can have a clearer parkour path throughout your map - this would also mean you wouldn't need as many barriers.
The difficulty is good for a medium map, but the length is far too long. Please read over this thread, 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.
