The document describes an idea for a two-player platform game where players are on opposite sides of a mirror and must use objects from each dimension to progress through levels, fighting a final boss to free their counterpart. The creator wants to develop an original concept and showcase their skills to earn a distinction. Initial influences may include platform games and animation references, without a specific desired effect on audiences beyond providing an enjoyable co-op experience. Promotional materials like posters and a trailer are planned in a pixel art style to fit the game's mood and ease animation challenges as skills are developed.
