Have you played Skyblock before? It is a fun survival game where you have to survive on an island in the sky and build up from there. This map introduces a shop system. To go to the shop, break the glass block, and you will fall and land right in the shop, just like magic. To get started, you must get enough of the free items from the shop to afford blocks. With those, you can expand your island into something bigger and start surviving and upgrading yourself.
