 Artificial Intelligence (AI) is an important part of many computer games, where it's often used to create dynamic challenges for players to overcome. In this problem solving task, your objective is to create an AI controller for a space ship in a simple 2D game. Survive for as long as you can by dodging incoming hazards, and earn a high score in Challenge Mode by shooting asteroids along the way. Welcome to Code Ship.
