Kick back in party mode! This doesn't add a lot, but it definitely serves as more of a "developer tip jar." If you liked Other Submarine and wanted to support the developer, you can buy this and kick back for some good times. Leaving the party sub through the ladder will show the full ending to escaping the Other Submarine.
