[STILL UNANSWERED] XxxLloyd061302xxX's Minigames script NOT WORKING! Fixes?

The title says it all, please be a nice person and help me through this. I am making my minigame with the tutorial made by XxxLloyd061302xxX. I also turn on FE for extra security, But it broke my game. He doesn't update the scripts to make compatible with FE. Due to the character limit, some of them will directly link to his script that I copied and used it in my game. (Forgot to mention I have less mind about scripting, IK how the RemoteEvents and RemoteFuntions work, but for coding to make it work, Roblox and others are explaining misleading and really IDRK when I put the code somewhere in the script) Thank you.
