Sam Duxbury created a sprite to represent the main player and an object for the player to add scripting to make it collidable and playable. Code was added to allow movement around the room. A room was created and the player object was placed inside along with a scrolling background. Particle systems were added to represent flames from the player. Enemies and projectiles were created so that hitting enemies would destroy them. Health and scoring systems were implemented using objects and scripting. Main menu and game over screens were built with interactive objects. Sound effects were imported and attached to rooms.
