Here's some feedback to further improve your code:
Try to restrict input to one word guesses or the full correct word.
Try allowing word detection regardless of casing. If the word is apple and user inputs 'A', it should be a correct guess!
Try asking the user to play again in the terminal without your program exiting, as another input (Ex. Play again? (Y/N) ).
Try adding a ReadMe to your project! Its good practice to have descriptive ReadMe's for all of your projects for recruiters and other developers to look at and understand your project! Your ReadMe could be the deciding factor of whether or not someone checks out your program. Also, recruiters do look for good documentation for hires since that's a necessary skill for job-readiness!
Try adding some tests for spaceman! You can try creating a sample spaceman gameplay situation by testing just the helpers. Is there a way you could throw errors in your test if certain conditions are not met?
