Hello caseyclosed and Leythis! I will be putting your map under review for the following reasons:
The Shovel Knight theme has been done before (ShovelKnight), so it's not entirely original, but not too bad.
The parkour is far too hard for an expert; there were a fair amount of jumps that were insane difficulty. Some of the jumps are also rather annoying. Lastly, moving pistons aren't allowed in maps, so those jumps will need to be removed. However, the length seems good and the parkour is varied and well-incorporated into the map.
The build is easily recognizable as the Broken Vessel and is well-detailed. Good job!
If you can make the changes needed, I am willing to accept your map. Once you're ready for me to test the map again, feel free to message me in-game, on the forums, or on Discord (MCBYT#2023).
