Generated from: a scene from a small video game about: Project Grenzfeste — editable top-down 2D LEVEL DESIGN PROTOTYPE (blockout only; no combat, economy, quests, characters or polished art). VIEW: top-down tactical level blockout on a world grid (roughly 9 vertical rows). It must read as one connected island, not three parallel corridors. WORLD STRUCTURE: - Castle/base at the FAR LEFT. - Exploration expands toward the RIGHT into a mysterious island. - Three broad biome bands: TOP (rows 1–3) = dense Forest (swamps, old ruins, winding paths); MIDDLE (rows 4–6) = Meadow/Grassland (open fields, abandoned farm, river crossing, bridge choke, ruined village); BOTTOM (rows 7–9) = Mountain (narrow pass, mine entrance, cliffs, high ground, tunnel). - Each band has enough vertical room for paths to bend, split and merge locally; they occasionally come close enough for one long-range tower to cover two, and rarely share a short natural choke (bridge, valley, mountain gate, ruined-fortress entrance) before separating again. SECTOR TEMPLATES (reusable): Straight, Bend, Split, Merge, Choke, Wide/Open, Safe/Risk Fork, Crossfire, Landmark, Resource, Story. Build ~10–12 revealed sectors, each roughly a 3x3 footprint (some wider/taller). Around 4–8 possible tower spots per sector, placed tactically (inside bends, long road exposure, chokes, high ground, bridge entrances, split coverage, crossfire) — some sectors strong kill zones, others awkward/distributed. ENEMY PATHS: draw real continuous paths from the RIGHT converging toward the castle on the LEFT. Paths may split into local branches and merge again (counting as one biome lane). SAFE/RISK FORKS: at least one fork with a safer route and a riskier route (riskier = better tower spots, better choke geometry, resource, landmark or better reward). The unused route stays visible but blocked/unexplored (e.g. overgrown forest path, destroyed meadow bridge, rockslide/collapsed tunnel). FOG / SCOUT SUPPORT: only the explored part is visible; the right frontier is hidden by fog where the island is assumed to already exist. No scout logic, but structure the map so a scout could later influence which biome is explored next, reveal upcoming sectors, enemy info, hidden paths, and safe/risk routes. RUN STRUCTURE: a full run lasts 28 in-game days; the map must NOT be 28 straight columns. Newly revealed sectors may go right, right-up, right-down, branch off the side, or form a local fork; the world stays fairly compact. VISUAL DEPTH → danger increases to the right: near-castle brighter/safer/natural; middle older/mysterious/with ruins; deep island darker/hostile/ancient. BOSS / END REGION: no single fixed universal boss spot. The most-developed biome during a run becomes the day-28 final region — show optional Forest, Meadow and Mountain end-regions, where only one may be reached in a run and the other two may largely stay unexplored. Goal: an editable tactical level blockout (castle left → procedural island expansion right, 3 recognizable biome regions, no boring straight lanes, reusable sector templates, meaningful tower placement, local splits/merges, occasional crossfire, safe/risk forks, blocked alternative routes, fogged unexplored frontier, support for a 28-day run) — a level blockout, not concept art, not a dungeon, not a flowchart., as an in-game screenshot in flat colour 2D shapes with a bright limited palette. Palette: sky blue #8ecae6, grass #3a7d44, player sunflower #ffb703, threat red #d62828, accent white #fdfcdc. Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one. Keep the pictures honest: they promise what a small first version of this game, made in a game engine in a few days, can look like. Simple readable shapes, clear silhouettes, few flat materials, the in-game camera view. Never film stills, photoreal renders, AAA key art, detailed textures, cinematic lighting, or anything that looks like a big-studio game. No text, UI, HUD, logos or editor screens inside any image.
