In terms of Fury Gunner, a game inspired by the Gunny, is an exciting Play & Earn game for players either from newcomers to professional level in order to test their skills and compete with their peers to create the "top-notch" shooting game, or even achieve a golden opportunity to participate in highly tactical games to ensure a great success.
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
FURYGUNNER.swapTokenForTokens(address,address,uint256) (#691-694) ignores return value by tokenC.transfer(account,amount) (#693)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.
