Create a fully playable web-based recreation of Minecraft that faithfully captures the core sandbox and survival experience, featuring an infinite, procedurally generated voxel world complete with distinct biomes, complex cave systems, terrain elevation, dynamic day-night cycles, and block-based lighting. The gameplay must fully support both Survival and Creative modes, allowing players to navigate in a first-person perspective, break blocks with varying hardness using appropriate tools, place blocks with accurate physics (including gravity for sand and gravel as well as flowing mechanics for water and lava), manage a grid-based inventory, and craft tools, weapons, and building materials through an authentic recipe system. Additionally, implement comprehensive survival mechanics such as health, hunger, fall damage, drowning, and tool durability, alongside a living ecosystem populated by passive mobs for resource harvesting and hostile mobs that spawn in low-light conditions to pursue the player, complete with functional combat hitboxes, knockback physics, and immersive environmental sound effects that closely mirror the original game’s atmosphere. Deliver a single, self-contained HTML file.
