Hello Franith,
I regret to inform you that your map is being rejected.
The theme is unoriginal, as we already have a few maps relating to mansions (Mansion, HauntedMansion.) However, the Medusa concept is original, so good job on that!
The build is good, although it looks a bit plain on the outside. The stone at the end of the map does look better, but I'd focus on adding more details to the beginning of the map.
The parkour is a bit repetitive, especially inside the mansion. I recommend using different jump styles throughout the entire map. You can look at recently accepted maps for examples of these! The parkour was also a bit confusing in certain points (especially the cake jump at the beginning,) so try to work on adding more signs to help show players where to go. I also think the map was a bit easy for a medium difficulty. If you want this to be a hard, try buffing some jumps!
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
