Hey Duckcrafter04,
Sorry to tell you that your map has been rejected.
The theme is not really original, there is already some mushrooms and slime maps (MushroomLand, GiantMushroom, SlimePK, SlimeBouncer), even tho there is not a map with the mix of those 2 themes, please try picking an original theme next time.
The build was also not really good, it's quite floaty and messy, please try building your map on/in a main build, avoid scattered builds if possible.
The parkour was okay, it was quite repetitive sometimes, but it's still kinda varied, however, I think the whole ladder with invisible blocks around the end is very confusing, please avoid overusing invisible blocks since we can't see them in survival mode.
Thanks for submitting your map, would be good to see more maps from you !
