Change the wording of difficulty requirement
I feel that "Above X difficulty" is a little misleading as that would imply that you need to play at a difficulty higher than the one stated, but in reality you can play at the difficulty it says. A better phrase might be "X and above" as to not confuse people. I went through the entirety of sky ship before realizing this.
Not a big deal or anything, I just though it would be a nice QoL change.
