Currently, we implement the following messages with parameters:

• CompletedRegistration when we create a new player profile

  • avatar_id
  • avatar_tint
  • gender
  • age

• AchievedLevel whenever we reach a new Journey Position

  • jp
  • st
  • lb
  • ps

• CompletedTutorial when we complete a tutorial phase

  • phase (enumerator index)
  • phase_name (for easier human parsing)

• SpentCredits when we use bones

  • nSpent (number of bones spent)

• custom_antura_customization, a custom message whenever we change the customization

  • "customization_json" defines the applied customization
  • "antura_space_play_time" how much time we spent in antura space

• custom_minigame_score, a custom message whenever we finish a minigame

  • "minigame_code"
  • "duration"
  • "journey_position" ID of the JP we are playing that in
  • score

With these, we cover the whole game.
I suggest we add:

• an event (or a parameter to SpendBones) to track what we spend the bones on
• an event on whenever we purchase a photo
• an event on whenever we obtain a reward, to track what we reward we give to the player (could be useful alongside the Customization event)
• time spent in the book
• daily reward obtained, with number of consecutive days
