- Introduced a new biome system with various biome types and properties. - Implemented terrain generation using Perlin noise to create diverse landscapes. - Added examples for basic tilemap generation and biome analysis. - Created helper functions for displaying tiles and biomes in the console. - Enhanced the TileMap class to support chunk-based tile management. - Developed a PerlinNoise class for generating smooth noise patterns. - Updated generation configuration to include climate parameters for biomes. - Implemented error handling for out-of-bounds access in TileMap.
