# Hidden Garden – stage chunks

The prologue, drawn from the approved [Hidden Garden concept](../../locations/hidden-garden-clean.md) as a flat side elevation with its figures removed. One chunk, `hg-0-0` (2160×720): the bench where Dexter sits at the start (x ≈ 190–320), the stone path and the timber jetty (path top y = 441), the end of the jetty where Dexter points (x ≈ 1290–1323), and one wrong patch in the pond's reflection below it – a rusty girder with a ladder that isn't there. Clean only.
The prologue, drawn from the approved [Hidden Garden concept](../../locations/hidden-garden-clean.md) as a flat side elevation: **five chunks, 10 800 px**, about 70 s of walking plus Dexter's waits and two detours ([docs/04 – Hidden Garden, the prologue level](../../../docs/04-WORLD-AND-LEVELS.md#hidden-garden--the-prologue-level), #50). `hg-4-0` is the approved pond chunk (the jetty where Dexter points, the wrong reflection). The four before it were grown leftwards from it with [grow_stage.py](../../../scripts/grow_stage.py) – scenery first, one masked repaint per route feature, the seams between new chunks repainted (docs/09): `hg-0-0` the gate (Dexter's bench, a birch log), `hg-1-0` the hill (an oak on the crest, a hollow behind the grass), `hg-2-0` the terraces (a shed with a ladder to its roof), `hg-3-0` the boardwalk (a gap with stepping stones). Clean only.

**Layers** (#142): the model repainted the chunk as a flat-colour depth key, and the masks come from it ([depth_layers.py](../../../scripts/depth_layers.py), [layers.json](layers.json)). Sky, far and mid scroll slower than the path (0.1, 0.25, 0.6, docs/04), and their plates are filled where the nearer layers hide them, so nothing tears open when the camera moves. The foreground scrolls at 1.2. [00 sky](layers/hg-0-0.00-sky.filled.png) · [01 far](layers/hg-0-0.01-far.filled.png) · [02 mid](layers/hg-0-0.02-mid.filled.png) · [03 rear](layers/hg-0-0.03-rear.png) · [04 water](layers/hg-0-0.04-water.png) · [05 play](layers/hg-0-0.05-play.png) · [07 foreground](layers/hg-0-0.07-foreground.png). The parallax at three camera positions: [parallax.png](images/hg-0-0-parallax.png) (`python scripts/compare.py parallax art/stages/hidden-garden`).
**Layers** (#142): each chunk's depth key comes from the model, its masks from the key ([depth_layers.py](../../../scripts/depth_layers.py), [layers.json](layers.json)). Sky, far and mid scroll at 0.1, 0.25 and 0.6 (docs/04) from plates filled where nearer layers hide them; the foreground at 1.2. The pond keeps its exact rules for path, water and foreground; the grown chunks take every band from their key. **Collision**: walk lines traced from each key's play band (`depth_layers.py collision`), spawns, Dexter's waypoints and triggers placed by hand; overlays in [collision/](collision/).

The whole walk: [prologue.png](images/prologue.png) · the parallax at three camera positions: [parallax.png](images/parallax.png) (`python scripts/compare.py parallax art/stages/hidden-garden`).

"style": "FORMAT: a STAGE CONCEPT for a 2D side-scroller explored in all four directions - one wide 2:1 image in strict side view, drawn like an architect's ELEVATION: every path, wall, bed and building runs PARALLEL to the screen from left to right; depth comes only from layers stacked behind each other, never from things receding toward a vanishing point; no path, corridor or bed leads into the distance. The hero is small, about one ninth of the image height. Build real level structure into the scenery: a main route plus at least one higher branch and one lower branch or underground pocket, smooth hills and slopes (some steep enough to slide down), ledges with grabbable edges, something to climb (ladder, vines, scaffold, stairs), a dead end with a small reward glint. DEPTH in clear layers: hazy far background, mid-ground, the play layer, and a dark, out-of-focus foreground of leaves and grass partly covering the bottom edge and corners as if the camera sits behind foliage; reflections where there is water; a few falling leaves. LOOK: detailed hi-bit pixel art, fine 2-pixel grain, the warm palette and light of the style master. TONE: secret horror - calm and pretty first. No text, no logos, no UI.",
