• Godot/Phaser-style top-down implementation

These prompts should generate individual assets or tiles, not full scenes.

8. Test in map.
9. Only then generate related variants.

Do not generate every asset in one batch

This will create style drift.

Recommended order:

1. Water, sand, dock.
2. Captain.
3. Fisherman.
4. Bottle and scroll.
5. Fishing net broken/repaired.
6. Dialogue and letter UI.
7. FX.
8. First playable mission.
9. Then expand Harbour.

Naming rule

Use stable asset names.

Good:

fishing_net_broken
fishing_net_repaired
fisherman_worried
water_tile_base
sparkle_success

Avoid:

nice_net_final
new_fisherman_2
better_water
asset_123

15. Prompting Rule for State Variants

When generating a second state of an asset, always include:

This asset must match the approved [BASE ASSET NAME] in:
- perspective
- size
- silhouette
- palette
- lighting
- outline style
- pixel density

Example:

Create fishing_net_repaired.

This asset must match the approved fishing_net_broken in perspective, size, silhouette, palette, lighting, outline style, and pixel density. The only change is that the torn holes are now repaired.

16. Prompting Rule for Top-Down Consistency

Add this line when the model drifts into side-view or illustration:

Important: this is not a side-view illustration. It must be a top-down 3/4 game sprite that can sit on a tilemap.

---

17. Prompting Rule for No Text

For signs, labels, scrolls, maps, and UI elements:

Do not include readable text, letters, symbols, or numbers. Leave blank space so game text can be rendered dynamically.

---

18. Prompting Rule for Mission Props

For any asset that will be used in a mission:

This prop should support interactive game feedback. Make the important interaction area visually clear and leave enough space for glow, sparkle, or letter/number overlays.

---

19. Prompting Rule for Godot/Phaser Readiness

Add this to final production prompts:

The asset should be clean enough to import into Godot or Phaser as a 2D sprite, with transparent background, no baked full-scene lighting, and no surrounding environment unless requested.

---

21. Final Reminder

The goal is not to generate perfect final art immediately.

The goal is to create a consistent reusable kit.

A good Harbour Kit v1 should let us build many missions from the same assets:

• repair net
• restore labels
• sort fish
• load cargo
• share fish
• unlock boat
• clear route
• receive first captain outfit

The kit is more important than any single image.
