The appearance of minis is randomly generated using modular pixel art pieces. The total possible variations is in the decillions... before clothing and accessories!!
Every mini NFT has inherent, immutable properties that are secured on the blockchain. These properties exist outside of any game, and it is up to each game to decide how to make use of them!
The minis are not just NFTs, they are functional rigs. They can be animated, equipped, and controlled. The NFTs will give access to playing the main game and all other future Pixil Mini games with the matching mini rig.
