Objective

Develop a Solidity (On Optimism L2) contract for managing game lobbies where players can enroll by depositing 0.05 testnet ETH:

Create a lobby system where a user can enroll in a game round.

• Limit the maximum number of players to 500 per lobby.
• Implement a deposit function to accept 0.05 testnet ETH.
• Ensure proper handling of overflows (more than 500 players) and underflows (lobby cancelation).
• Maintain a record of enrolled players and their deposits.
• Bonus: Add a feature for refunding deposits if a lobby is canceled or a player withdraws before the game starts.
• Ensure ETH is stored safely in vault
