How it was built

This is an in-house LuckeySystems project, not a benchmark run. It was built here with AI assistance across many sessions, with a human directing the work — so there is no single prompt to publish and no one-shot claim attached to it.

Filed as studio rather than bench. The run directory holds a screenshot trail — gameplay, gameplay_v2, gameplay_v3, inventory_v2 — interleaved with edits to the game over about twelve minutes, so this was refined by looking at output rather than written in one shot. The same rule already excluded Qwen’s first VoxelCraft pass from the bench.
