Game Build - Audit

In the contract `GameBuild` and `GameBuildSwap`, the role `_owner` has the authority to update the status of the `whenNotPaused` function and further pause/resume the functionalities of this project. Any compromise to the privileged roles may allow hackers to take advantage of this authority and disable the users' actions.

The GameBuildSwap smart contract facilitates the swapping of two types of tokens (`tokenCRE` and `tokenSLG`) for another token (`tokenGameBuild`) based on predefined ratios. This contract is designed to allow users to convert their CRE and SLG tokens into GameBuild tokens, potentially during a migration phase or as a part of a game ecosystem's economic rebalancing. The issue in the contract's design is the absence of any restrictions or conditions on the timing of swaps. Specifically, the functions `swapCRE` and `swapSLG` lack mechanisms to prevent swaps after a certain event, such as the end of a migration period, other than the total available balance of `tokenGameBuild` in the contract. This oversight could lead to exploitation, especially if the market value of `tokenGameBuild` increases significantly compared to `tokenCRE` and `tokenSLG`. Users could potentially swap their CRE and SLG tokens for GameBuild tokens at a rate much more favorable than current market rates in the contract, leading to a sudden influx of GameBuild tokens in the market and potential devaluation.
