I got a lump of coal on my first playthrough because I didn't know the keywords were supposed to be clicked on, haha. I was using Enter to scroll through the chat, and I thought those blue keywords were just things I had to commit to memory that I'd be quizzed on later.

I played it properly the second time through, though! I like the idea of interpreting the character's text and strategically choosing when best to click on the keyword. Unfortunately, the game crashed when I clicked on two keywords one after another. But I liked what I saw while I was playing!
