CHOICES: I suppose I thought your positively / negatively choice was brilliant because it gave the story an element of suspense. At first the audience was a passive observer, but suddenly there is a clear split in the path and you - the player - have been given the controls. Call it basic, but it surprised me and I liked it.
TEXT PARAGRAPHS: I guess it's a matter of opinion then. I just feel that having slightly larger text and limiting to 3-4 lines per click would be beneficial and worth the extra clicks. Perhaps illustrations next to and behind the text box make harder to focus on a full paragraph, or it could just be what I'm used to for dialogue in similar media.
