In another life — well, about 4 years ago — I was the brand designer for a web3 NFT project, and I have never bragged about it. I'm about to! The story was incredible, one guinea pig 🐹 trying to escape a laboratory to find his love, which was taken for testing. Along the way, he meets 7 other characters who try to overthrow the lab. —PT 1 (I have more visuals I want to share! Why only 4 Contra? ;))
