Moo monster is play to earn (P2E) games are completely free to play and require no investment. Each player may have or not have non-fungible tokens (NFTs) in order to participate in the game. Certain NFTs can be acquired through the use of MooMonster Token (MOO) in the market or through the use of in-game gifts. Certain NFTs will be transformed into characters that the player can bring into battle. Each stage requires the player to form a team uniquely and properly. At the conclusion of the game, the player will receive the gift, which is a Golden Piggy Coin Token (GPC) limited to one per day, as well as any additional gifts, such as NFTs or game items.

Pragma version0.8.10 (contracts/tokens/MooMonsterToken.sol#2) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
