Great game so far; I wish you the best of luck in future development.
One item I would like to see more of is the phone. It's an excellent multitool that you can use for different purposes throughout the game, whether it be major or minor side content.
For example
A side event that could be added but doesn't affect the player much is that you could flesh out the Livestream app for players to watch random streamers' videos. Additionally, you could use other apps to meet new people, acquire "special" items, or some other event. Such as a Pizza delivery app, A local news app, and whatever might fit the game.
I wanted to say these ideas, as I think the phone/apps would be a great way to add future content. Keep up the good work.
