Asteroids meets a racing game.
Planets have decided to start delivering pizzas to offset operating costs (gravity isn't free). You are competing to be the top galactic pizza delivery planet. Race against other planets to see who can get the highest tip. Catch is, all your ingredients are floating in space and you collect them as you go. Make sure the order is correct and you don't hit any asteroids on the way.
The game starts with the player chosing a planet to represent. Afterwards they will be matched with another pizza deliverer. Each of you will receive a pizza order saying what ingedients to collect (e.g. dough, cheese, peppers, tomatos, etc). After a countdown, the players will be given the signal to start the race. Both players will occupy the same track in space and will be competing with each other for ingredients. Colliding with an indegredient will add it to your collection count. Collide with an asteroid and you will lose some time. If you collect ingredients that werent requested, then you will lose money from your tip. At the end of the race, the players' speed and order accuracy will be used to calculate their final tip. player who recieves the highest tip wins.
