Critterz is an NFT project based on the Ethereum blockchain that implements Play-to-Earn mechanics in the Minecraft game world. Minecraft is a 3D construction (sandbox) in the first person with minimalist graphics. You play as your first-person character, mine minerals, breed animals, grow plants, fight enemies, and, of course, build structures of varying levels of complexity from 3D game blocks. You can have up to 8 in-game characters and earn money from NFT items.
