Win a big fight

Generated from: a scene from a small video game about: Create a comprehensive game design document for an action-RPG based on the following detailed specifications: Premise & Lore * Core Narrative: The player takes on the role of an entity born pure darkness whose sacred duty is to protect the Dark Fountain from being sealed by "Lightners"—beings originating from the real world. * Objective: Defend the Dark Fountain against relentless waves and incursions of Lightners while continuously growing stronger, evolving dark magic abilities, and upgrading powers. Player Character Visual & Aesthetic Concept * Appearance: A pitch-black knight defined by a high-contrast white outline, a diamond-shaped head, and striking antlers, wielding a massive long black sword. * Visual Trait: Constantly hovers and floats off the ground, leaving behind a persistent trail of dark motion-afterimages projecting in the direction opposite to movement. Required Gameplay Systems & Mechanics * Mobility Mechanics: Outline 3 distinct aerial mobility modes (e.g., high-speed dash, vector-based reverse glide, precision phase-shift) that dictate both movement and positioning during combat. * Combat & Abilities: Detail a full suite of sword strikes, dark magic skills, and defensive maneuvers designed for fast-paced action. * Progression System: Design an upgrade framework showing how the knight continuously gains power, unleashes new abilities, and evolves stats to handle increasingly strong Lightner invaders. * Enemies & Bosses: Provide dynamic Lightner class archetypes (e.g., Paladins, Mages, Sealing Specialists) and outline a boss battle structure centered around defending the Dark Fountain. Please organize this into a fully structured, modular design document featuring controls, skill trees, level design concepts, and core gameplay loops. And make it all 3d with mobile controls. The player in the middle of a big fight. Drawn as finished full-colour game concept art in a clean, neutral style: clear shapes, readable silhouettes, soft even lighting, a balanced palette. Never a sketch, pencil drawing or line art. Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one. Keep the pictures honest: they promise what a small first version of this game, made in a game engine in a few days, can look like. Simple readable shapes, clear silhouettes, few flat materials, the in-game camera view. Never film stills, photoreal renders, AAA key art, detailed textures, cinematic lighting, or anything that looks like a big-studio game. No text, UI, HUD, logos or editor screens inside any image.
