Warning- Using the guide can take the fun out of discovering how to play. If you are stuck at a part and don't know where to go, you've come to the right place.
What you want to do first is to make a cobblestone generator. This will provide a solid sorce of blocks to expand your island with. Using your fist, you will need to make a 2×2 square in the dirt. Break the two ice blocks, each in one corner of the hole.
From there you can start making a cobble generator.
