While discussing the early stages of Space Mail, we the writing team thought it would be best that the story is through statically programmed check ins, depending on where the player is on the leaderboard.  For example, as you complete your delivery journeys on a planet, if the player moves up to the 5th spot on the leaderboard after all the minigames have been completed then there will be a cutscene that progresses the narrative before moving onto the next planet. Since Space Mail was more gameplay focused it was tough to find a spot to help us flesh out a story during this game. But with some direction from our studio manager we were able to create a narrative that fits well within a gameplay heavy game.
