Create a 2D top-down dark fantasy maze game in pixel art style. The player controls a knight who explores randomly generated dark mazes filled with monsters. The goal is to find a hidden chest containing a key and a better sword (level 2, 3, 4, etc.). Each maze level increases in difficulty: Enemies become stronger and more numerous The sword inside the chest gets one level stronger The color scheme is dark and moody, with pixelated graphics and colors like deep purple, green, and black. The knight uses melee combat (sword swings) to defeat mobs. Add a simple HUD showing the current sword level and health. Include basic sound effects for combat and chest opening.
