Thank you for the feedback! We did have more minigames planned, but had to cut them due to time constraints.
We did want a diary to be the main focus, but I can see how that would seem unnecessary in today's day and age. We probably could have flushed out the story more to make sense of the diary if we had enough time.
The age was added to make sense of a small part of the story which in retrospect made other parts seems off. We will surely look out for such details in the future. Thank you for taking the time to write your thoughts!
