rimlike — art / tileset strategy

Companion to memory.md. This file is the art strategy: owned tilesets (now substantial), aesthetic anchor, gaps, license notes, autotile gotchas.

Aesthetic anchor

Primary: ElvGames "Ultimate Farming RPG" bundle (Humble) — cute-farming-RPG palette.

The aesthetic shifted on 2026-05-10 when the bundle was found. Previously locked as "vibrant medieval-fantasy" via Ventilatore + planned Mana Seed; now the spine is ElvGames' bright, cheerful, Stardew-adjacent farming-RPG style. Project tone: "Going Medieval × Stardew × Rimworld" — cozier than Rimworld, deeper than Stardew, mobile-first.

Ventilatore Fantasy Tileset Bundle (already owned) stays as a secondary layer for biome variety, decorative props, and medieval-flavor accents. Mana Seed series is dropped from the buy plan entirely (the bundle covers what we'd planned to purchase).

Owned art foundation

Secondary — Ventilatore Fantasy Tileset Complete Bundle

Owner: us. Bundle URL: https://itch.io/s/117124/the-fantasy-tileset-complete-bundle. Six packs, 16×16, vibrant medieval-fantasy.

Use as: decorative flourish — animated water, encampment props, medieval fences, foliage variety, bridges. Where ElvGames' farming-RPG palette feels too cute, slot in a Ventilatore prop.

Skip: prefab houses (wrong paradigm), most exterior buildings (ElvGames covers them).

Pack file structure

ElvGames packs are consistently structured:

<Pack Name>/
├── Characters/        # NPC sprite variants per pack
├── Item Icons/        # category-relevant icons
├── Objects/           # decorative / interactive objects
├── Tilesets/          # main tilesheet PNGs
├── RPG Maker/         # RPG-Maker import format (ignore)
├── License.txt
├── Read Me.txt
├── *.unitypackage     # Unity import (ignore)
└── *.yymps            # GameMaker import (ignore)

For Godot: import the Tilesets/*.png directly as TileSet sources. Objects + Item Icons are individual sprite assets.

Gaps still uncovered

Even with the bundle, these need authoring or sourcing:

1. Autotile-ready buildable wall sets — UNKNOWN. The bundle's house and fortress sheets need an autotile audit (count corners / T-junctions / cap pieces). If insufficient, options are:
   • Custom-author terrain bits onto bundle wall tiles (~half-day per material)
   • Source a dedicated construction tileset (Mana Seed Iconic Homestead remains available as fallback at $19.99)
2. Designation overlays — blueprint ghosts, chop-this-tree marks, mine-this marks. ~4–8 tiles, custom (~2 hrs).
3. Indoor tint shader — a subtle blue-grey overlay on Layer 0/1 tiles when Roof flag set. Not asset, just shader work.
4. Lighting shader — for visual lighting at night (we locked this in mood/lighting). Not asset.
5. Cleaning visualization — dirty-tile decals. Some bundle packs (Mines? grass spring etc.) may have grunge tiles we can repurpose.
6. Wolf sprite — bundle's Animal Sprites pack does NOT include wolves. Options:
   • Reskin a different animal (a darker dog?)
   • Pick a suitable wild creature from EvoMonster Pack series
   • Custom wolf sprite (a few hours of pixel art) or external pack
7. Cremation pyre furniture — may be in House Interior or Marketplace; otherwise custom.
8. Grave marker tile — likely needs custom or graveyard-themed pack (Retro Graveyard 16×16 in Tier 3 might have it).

Audit list (action items before any release build)

• Autotile coverage of Houses Tileset 2 Seasons/FG_Houses.png — count corner/T-junction/cap pieces for player-built walls.
• Autotile coverage of Fortress Tileset 2 Seasons/FG_Fortress.png (alt material).
• Aesthetic harmony test: open one tile from ElvGames Forest 4 Seasons + one from Ventilatore + render in same scene. Is the palette cohesive enough to mix? Decides whether Ventilatore stays as accent or gets shelved.
• Wolf sprite source — confirm what's available from EvoMonster / Turn-Based Monster packs; if none, plan a custom.
• Confirm Retro Graveyard 16×16 has grave-marker tile we can use.
• License attribution credits document — list every pack we use, credit string for game credits screen.

Tileset prep (the gotcha)

ElvGames packs are RPG-style — designed primarily for RPG Maker / GameMaker hand-painted maps, not tile-by-tile colony construction. Same caveat as Mana Seed: walls and floors may not have full 47-tile autotile coverage. Plan for ~half-day per buildable material to author Godot terrain bits onto the existing tiles.

Designation overlays still custom. Estimated 4–8 tiles, ~2 hours of pixel art.

License notes

ElvGames terms (most packs in the bundle):

You can: use in personal or commercial projects. Edit/modify to fit your game. Credits to ElvGames. You cannot: use in NFT/crypto projects. Sell this asset pack (even modified). Claim it as your own.

Source: License.txt in each pack. Full terms: https://elv-games.itch.io/terms

Some packs may be by other authors (e.g. Retro Kingdom Explorer series). License for each is in the pack's own License.txt. Audit and honor each.

Ventilatore terms: confirmed commercial-friendly during prior owner-of-bundle research; verify before any commercial release build.

Credits screen requirement: maintain a list of pack names + creator names; display in game's credits UI.

What was dropped from the plan

• Mana Seed series purchases — Smithing Gear, Crops #1, Iconic Homestead. Bundle's coverage replaces them. Free Mana Seed forest packs and Character Base remain optional fallbacks if Bundle palettes mismatch a specific need.
• Gold Rush / Pixel Farm RPG / LimeZu / Cute Fantasy / Mars Colony — all dropped from active consideration; bundle covers their roles.

Comprehensive survey (kept for reference)

Earlier-session survey of itch.io / OpenGameArt candidates (now superseded). Maintained so future sessions don't redo the search.

• Mana Seed by Seliel the Shaper (itch profile) — only tileset family explicitly authored for tile-by-tile player construction. Free seasonal forest + Farmer Base remain optional fallbacks.
• Iconic Homestead ($19.99) — fallback if bundle's wall autotile coverage is insufficient. Stone/wood/plaster wall variants explicitly construction-authored.
• Modern Interiors / Exteriors by LimeZu — modern aesthetic, wrong direction.
• Cute Fantasy RPG by Kenmi — Stardew-adjacent (similar to bundle's tone, could supplement).
• Base Building Tileset by Eli Haun — Rimworld-genre match but small.
• Colony Sim Assets by Buch — CC0 fallback.

Reading list (TBD)

• ElvGames license fine-print on each pack used.
• Godot 4 docs: TileMap, TileSet terrains, AStarGrid2D.
• Rimworld design talks (Tynan Sylvester) — storyteller / drama / interest curve.
