Build Isometric ARPG

Build one coherent playable loop before expanding scope: title/menu, character choice, movement, one encounter, reward, progression, and continuation.

Establish the production contract

1. Inspect the current game entry point, scene loop, content model, controls, save model, and tests.
2. Record the authoritative baseline before integrating dependent work. Preserve unmerged work and do not build from a stale branch.
3. Define data-driven contracts for player classes, equipment, enemies, zones, encounters, quests, and review fixtures. Keep authored content separate from runtime state.

Build in vertical slices

Deliver each slice with a playable route and deterministic test state. Prefer this order:

1. Movement, camera, collision, target selection, and pause/restart.
2. One combat verb plus contact, damage, posture, recovery, and death.
3. One enemy with telegraph, decision loop, and counterplay.
4. One reward and atomic inventory/progression update.
5. One zone transition or objective completion.
