As a player, you'll have a snook-character that's an NFT. By advancing in game (eating everything, avoiding and killing other snooks, and taking their traits), you'll rack up achievements like traits and rare skins. Blockchain and Crypto technologies let us record these achievements immutably (think of it as a "barrel" in Blockchain/Crypto terms). You can access your game character/NFT later on for other games or commercial purposes, and - under specific conditions - get financial incentives from it.
