I have made a map of Hard difficulty on the Minevast Creative Server. It is called Path to Demon, with the map revolving around a soul sand monster. There are 70 jumps and 6 checkpoints. You can get to this map by using /warp DemonPath, which was set by CrimsonTiger AKA tiger67456. The creator of the map (me) is happyheart.
