In the selection level panel, all levels are awarded a difficulty rating.
Toxic Swamp : 2
Shrooms Grotto : 3
Red Thorns Tower : 1
Underground Plant : 4
Cool Island : 3
Ice Rocks : 9
Giant Forest : 7
Acid Hills : 8
Lava Cave : 10

I would like to update those difficulty levels ranging from 1 to 10.
Please tell me, what difficulty ratings would you give to those levels ?
