In Blocksworld, the basic shapes are common, three-demensional shapes like cubes (blocks), cylinders, ramps and half blocks. They are the easiest blocks to get and most convenient shapes in the game, being able to be used for almost any purpose.
Blocksters are the humanoids or with specific animation that you can't create yourself. The original version has a red hoodie if male, and a purple sweater if female. The animal versions require the user to build them with blocks and leg pieces. For example: when you are building a cat, you will need a cat face on a cube block, one set of four legs and a set of ears. You can equip hats or hairs to your Blockster, as well as chestplates, capes, and items for your back. Some parts of your Blockster can be colored and textured.
