    A battle game for any of your EVM blockchain NFTs▲6

    Hey everybody, I've been building a battle game where the world of NFTs meets Super Smash Bros. It works with most standard ERC721 NFTs on Ethereum, Polygon, and Arbitrum. The game takes your NFT, crops it, and puts it into a mech suit with guns. I'm still building out the features such as multiplayer and custom mech suits and additional power ups. If you are into NFTs I would love you to try out this early single player version and give me your feedback.
