some tips:

1. If you want an editor exposed variable but slightly faster, use [SerializeField] private GameObject example;
2. Consider using public const string over public string if it's going to be used every time your game is active
3. (Preference) Use the new Input System over the old one, as it offers better performance by skipping Update loops
4. Avoid adding strings together like $"{stg}_5_win.mp4" as it generates memory garbage, instead import ZString and use ZString.Concat(stg, "_5_win.mp4")
5. (New C#) You can replace stg != 5 with stg is not 5, stg == 5 with stg is 5 and same with strings etc. Note that this only works with constant values, so no dynamic ones
6. Create a new System.Random instance as a global variable, rather than a method one. private readonly Random rand = new();
7. Avoid using boxing like (int) as it is often extremely expensive to do and can generate memory garbage
