Connor Martin created a basic player sprite for a 2D space shooter game. He designed his own spaceship and created code to make the player sprite an object that can move, shoot, and explode in the game. Connor then created a basic background and tested the player controls. He added particle effects to the player object to resemble an engine jet and coded projectiles to fire when the spacebar is pressed. Connor designed enemy sprites, spawn and movement systems, and explosions. He also added enemy projectiles, a health bar, damage system, and score counter to complete his 2D space shooter game.
