How best to estimate my game's playtime?

Ah! No, my confusion was that you had posted that it told you how many words it went through, whereas in my result I didn’t see that. I figured out why, though - you need to tell it to print the full text to get the word count. I got it - apparently my game is around 39600 words for one playthrough.

…which, if people are reading at 200-250 words per minute, whoof, I’m way over my word budget. Oh no! I’m going to have to cut a lot!
