GamerZilla._liquidityUnlockTime (#1060) is never initialized. It is used in:
- GamerZilla.getLiquidityReleaseTimeInSeconds() (#957-962)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

GamerZilla._swapContractToken().tmpSuccess (#924) is written in both
(tmpSuccess) = address(TeamWallet).call{gas: 30000,value: distributeBNB}() (#924)
tmpSuccess = false (#925)
Fix or remove the writes.

GamerZilla._swapContractToken() (#901-926) performs a multiplication on the result of a division:
-tokenToSwap = sellLimit / 5 (#904)
-tokenForLiquidity = (tokenToSwap * _liquidityTax) / totalTax (#910)
Consider ordering multiplication before division.

GamerZilla.BlockBots(address[]).i (#784) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

GamerZilla.burnLiq() (#1064-1079) ignores return value by _pancakeRouter.removeLiquidityETHSupportingFeeOnTransferTokens(address(this),amount,0,0,address(this),block.timestamp) (#1069-1076)
Ensure that all the return values of the function calls are used.

GamerZilla._approve(address,address,uint256).owner (#1127) shadows:
- Ownable.owner() (#221-223) (function)
Rename the local variables that shadow another component.

GamerZilla.TeamUpdateLimits(uint256,uint256,uint256) (#1029-1037) should emit an event for:
- balanceLimit = newBalanceLimit (#1034)
- sellLimit = newSellLimit (#1035)
- buyLimit = newBuyLimit (#1036)
Emit an event for critical parameter changes.

GamerZilla.SetupLiquidityTokenAddress(address).liquidityTokenAddress (#1055) lacks a zero-check on :
- _liquidityTokenAddress = liquidityTokenAddress (#1056)
Check that the address is not zero.

GamerZilla.getAddressSellLockTimeInSeconds(address) (#977-984) uses timestamp for comparisons
Dangerous comparisons:
- lockTime <= block.timestamp (#979)
Avoid relying on block.timestamp.

solc-0.8.7 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.

Low level call in GamerZilla.sendBNB() (#1081-1084):
- (sent) = TeamWallet.call{value: (address(this).balance)}() (#1082)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable IPancakeRouter01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#80) is too similar to IPancakeRouter01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#81)
Prevent variables from having similar names.

sendBNB() should be declared external:
- GamerZilla.sendBNB() (#1081-1084)
Use the external attribute for functions never called from the contract.
