I need new modification in the game that I'm have in the upload files. The game should have allowed users to logon on with a username and password. Store an artifact of the username and password on the computer. The users should not be able to read the usernames or passwords if you choose to store them as files. The game keeps a running score for each user. The game tracks user score and allows the user to continue the game the next time the user returns. When a user starts a game: log their score, date, and time. When a user chooses to terminate their game: log their score, date, and time. The game should detect if it is being manipulated. This modification will be tracking scores. Detect if someone tries to start a game with a score different from when they last terminated the game. This modification will be tracking usernames and passwords. Detect if someone is adding users or manipulating their passwords. Upon detection of manipulation, the modification should announce it.
