2nd paragraph and image

On page 67, talking about the Social engagement loop, the sentence above the image doesn't align with what is shown in the image. The text says Motivating emotion, then Player Re-engagement. The image however festure Motivation emotion then Social call to action. So, which is the correct flow? I bought my book from Amazon using the Kindle app on my iPad.

Figure 4-7

Figure 4-7 shows the social engagement loop as Motivating Emotion ➔ Social Call to Action ➔ Player Re-Engagement ➔ Visible Progress / Reward However, in the text and in all examples (e.g. on pp. 68 and 69), the loop is actually (and more logically) described as Motivating Emotion ➔ Player Re-Engagement ➔ Social Call to Action ➔ Visible Progress / Reward

4th paragraph

There are 2 code snippets: class User belongs_to : level ... class Level < ActiveRecord::Base has_many :users ... And in the next sentence: This describes the "User has many Levels" relationship... I think it must be: This describes the "Level has many Users" relationship... Because every user has only one current level (level_id), but one specific level may be achived by many users. As also said by the code snippets.
