Ultimate Sunflower Creation also known as "Yuuka Minecraft", is a sandbox game based upon Minecraft, an indie game developed and published by Mojang. Set in a vast open area and without specific storyline, USC allows player to roam freely through a flat 2D world and is given considerable freedom in choosing how or when to approach objectives such as exploration, gathering resources, crafting, and combat. However, the game has two definitive objectives: survival where players have to gather natural resources and maintain their life, and creative where players can make various things such as building house, library, etc.
