When player has a key in their inventory and attempts to pick up a second key, the game displays the "You've found a small key !" message but game doesn't store or register the second key in the inventory.
Once this happens, there is no way to get this key again and the player is locked out and has no choice but to reset the game to continue.
The game should allow the player to hold more than one key or outright not allow the player to pick up a second key (ie. player cannot do a key puzzle while there is a pre-existing key in inventory).
