SkyCraft is based of the popular map, SkyBlock. There will also be multiple different islands for you to explore. Some will contain dungeons. The nether will be more or less normal but with custom structures and dungeons. I will try to make everything in the game available. With the 1.13 update i'm going to make beds accessible as early as possible so phantoms don't ruin your experience. A challenge list will be added soon along with more pictures and info.
Thanks and have a nice day!
