hey, i think you should, when you add dragons, that there is a nest and you can steal an egg and raise a dragon from a baby. Also if you raise one you can ride it :goldore:. you should also add guns, like flint locks, and bigger boats so you can move your materials to a new island if needed. fish as a food source sounds good too, horses to ride is good too if you can't get an egg.
Also, you should be able to create a back pack out of leather to put more resources in as you go. like if your in a mine and you find diamond but you have an inventory full of coal, redstone, wood, and iron you and make a workbench and create a Back pack if you have leather oo have one before you come down.
