I am new to this and I need to know how I can keep score that increases every millisecond you live.

And how to keep a best score

And how to make a character "die" and start over.

1) put in draw actor code:
score += 1;
It will increase your score every frame

2) You can save and load variables with loadVar and SaveVar. It will use external file to store data

3) Can you describe more the die and start over question
