Thanks Errol! Very appreciated. You can get an S rank, but not an A+.
Getting an S rank, to be fair, is very subjective (rather than objective) to my whims! So it involves doing and not doing certain things!
Also, I've been getting feedback from non-text-adventure players and younger kids, telling me theyre finding it too hard (Hmmmm...) so i've had to 'consolise' it by adding a reminder prompt every 5 turns!
