In Game.sol No one is able to claim the throne due logical error

Description

A critical logical error in the Game.sol::claimThrone function prevents any user from successfully claiming the throne effectively making the game unplayable.

Root Cause

This condition allows only the current king to proceed, which is the opposite of the intended logic. According to the game rules, the current king should NOT be allowed to reclaim the throne. The check should prevent re-claims by the same address, not enforce them.

As a result:

• When the contract is first deployed (currentKing == address(0)), any attempt to claim the throne fails because the user is not the king.

• Even when the throne has not been claimed yet, no address can ever succeed, because the check only allows the current king to proceed, which defeats the purpose.

Risk

Likelihood: HIGH

• Every time when someone is trying to claim the throne. Even when the king has never been set to a player

Impact: HIGH

• Makes the Game unplayable for everyone.

Proof of Concept

This require stateme checks whether the user is a king, if so than only proceeds to further execution which is totally opposite of what protocol has intended to which not letting king to re claim the throne. In this case, it will revert with the error. Paste the following code inside the Game.t.sol

Recommended Mitigation

Apply this changes to overcome the issue inside the Game.sol::claimThrone function.
