Early returns

#1

why I think we have to order the checks

example: if the player should not lose a life on guessing a word that is an isogram so if we put the statement that says to if we don’t get the hidden word right then decrement a life he will lose a life before the check for isogram starts so he loses a life for no reason

#2

I finally (after a long time) understood what the early return is for. (I guess)

I have some insecurities still about writing code, I’m not 100% confident on if it’s properly wrote or if it’s garbage.

I wanted to post my work this far and maybe get some feedback to know if it’s on the right track or is there something I could improve.

Thanks a lot!
