Hello Virosisbae,
Unfortunately I will be
Rejecting your map,
The theme isn't very original, as it's based around a minecraft block, there are already minecraft item based maps, I would recommend looking at this thread
https://manacube.com/threads/parkour-list-with-theme.20194/ so you can see what themes are/aren't original.
The parkour doesn't have much variety, as it's mainly single blocks and slimes. I would suggest experimenting more with different blocks and items when creating parkour.
The length of the difficulty was good for an easy, however the parkour was probably too easy, except for the neos at the end.
Thanks for submitting your map! I hope to see more maps from you in the future.
