There could be other uses for this game.
Since the game is called Lake and there are boats in the game, it would be nice to travel around and do something else other than delivering mail.
Yes, it would be nice to rent a boat and drive it around the lake.
It would also be nice to be able to fish in the lake.
Things like that.
Optional things like that, would keep people playing the game even after they finished it.
But yeah, it's sort of a great game if you want something cozy and relaxing.
It's also great for the social interaction between characters.
In a certain way, mimics reality, mimics real life.
It's like taking to a friend in real life, but in this case, it all happens inside of a game.
