About this game

An isometric action RPG in the Diablo tradition, built on three.js WebGPU with a vgpu compute layer sharing the same GPU device. Pick one of three classes and go down. The Warden holds the line with steel and shouts. The Stalker kills from outside the fight and leaves before it arrives. The Ashcaller trades life for reach. Each has three skill trees, fifteen skills, prerequisites and level gates, and synergies that make an early skill worth points at level forty. Everything the genre runs on is here and none of it is decorative. Four main attributes feeding roughly fifty derived stats. A grid inventory where a two-handed sword costs you four cells and deciding what to leave on the floor is part of the loop. 147 item bases across normal, exceptional and elite tiers, 110 affixes gated by area level, 24 uniques, four set families, 25 gems and sockets to put them in. Twelve monster archetypes, three bosses, sixteen elite affixes that stack into monsters worth running from. Fifteen hand-defined floors across four acts, then an endless descent that keeps going as long as you do. Levels are generated per run from a seed: BSP dungeons, wilderness, caverns and boss arenas, each carved out of solid rock and lit by torches you can see going out behind you. Monsters path with a flow field, take line of sight seriously, and telegraph every attack — the rule the AI is built around is that a hit you take is a hit you could have avoided. Dust hangs in the crypt air, embers rise off the forge floor, and both are simulated by a compute shader rather than faked. Original art throughout: every icon, every HUD frame, every piece of key art. CC0 models from the OriginGame asset library, credited in full.
