Crea is an easily moddable, 2D sandbox game with a lighthearted mood, colorful art and RPG elements. Drawing on the pioneers of the sandbox genre such as Minecraft and Terraria, Crea features combat and crafting in attractive, randomly-generated worlds for you to explore, tear apart and build back up in your own design.
