Construction blocks are the main building tool for Blocksworld, and can be enlarged, moved, and turned to create contraptions or figures to your imagination. Some blocks have hitboxes or restrictions that don't allow them to stretch or be enlarged to a certain direction or extent. All blocks have a hitbox and when attempting to place or stretch a block into another, it will automatically take the block to the nearest point of the drag. Most blocks can be textured or colored by dragging the texture/color of choice to the block.
There are many different types of blocks in the game. The traditional cube is commonly used in most worlds. Triangles, spheres, semicircles, and corners also make an appearance. Certain blocks can only be unlocked by buying a game set or buying a block from the item shop.
