2023-04-21 updates:

-- put in choice at the start to enter Normal or Hard mode, so the user knows they're there.
-- clarified use of P to list progress and sequences. PP and PPP now show more detailed and potentially spoiler-y stuff.
-- colorama loader tweaks. We can now proceed without colored text, with asterisks provided in place of colored text.
-- more game text has colored text formatting now.
