A top down game where players play as a mailman and the objective of the game is to deliver packages to different locations. The player gets paid if a successful package is delivered and the amount depends on how quick their package arrived and the state of the package. I the player hit's too many obstacles on the road the quality of their package goes down and they will get paid less. The player can use this money to buy things that will help them deliver future packages more efficiently. Eg (Van, truck, motorcycle). Once unlocked, the player can choose which vehicle to take to deliver their current package. Unlocking more vehicles will mean that the player will be able to deliver a wider variety of packages that can get them paid more. There is no end and the player just plays for as lock as he/she likes.
