Update!
The game now has a new gun after you've survived over 60 seconds. Enjoy!
This game is quite an experience. It had very little in it, but the people that left messages in the bottles made the experience truly nice to play.
In my playthrough, I didn't have anyone to talk to, but reading and responding to the messages in the bottles made me feel lonely. Like the messages are about people trying to reach out to someone else, and you can't reach back out for them. But despite that lonely first experience, I think I'll play some other time.
Good job!
