Hoi SilverFoxi,
Sorry to tell you that your map have been rejected.
The theme is pretty interesting and original. The build however is not really good, there is a lot of floating blocks in your map, making it messy and unattractive, I also think the character you made could be better. The parkour is not really good too, I found your map pretty repetitive (A lot of ladders and normal jumps) even if there is some slimes, I suggest you to use ice, soul sand, fence.. in your parkour next time !
Thanks for submitting your map, would be really good to see more maps from you !
