Heartlock Academy

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Recreate a playable Three.js-style 3D anime-inspired stealth/social academy prototype titled “Heartlock Academy.” Use a small third-person courtyard viewed from a perspective orbit camera behind and above the player; the camera smoothly follows the protagonist and can be rotated by mouse/touch drag. The world is a bright, stylized low-poly school campus under a pale blue sky with fog: a large green lawn, cream-colored cross-shaped walkways, a pink-and-white academy building/classroom area at the rear, rows of classroom desks visible inside/near the open academy area, a circular stone fountain with blue water on the left side of the courtyard, and evenly spaced cherry trees with brown trunks and pink rounded canopies. Use soft directional shadows and cheerful pastel materials. Characters should be simple, faceless/low-detail humanoid game models with distinctive colored anime-style hair/accessory pieces and floating dark translucent name plates. The protagonist is a dark-haired student with a pink accent, starting near the front of the courtyard; movement is WASD/arrow keys or a mobile virtual joystick, with movement relative to the orbit camera. Include idle/walk/run animations when available and basic collision with the academy walls and world bounds.

Implement the core loop: explore the campus, talk to students to learn their personalities, recruit eligible non-rival students as followers, choose a non-graphic method to remove the rival, avoid witnesses and suspicion, then return to Senpai for an ending dialogue. The player can press E or tap a Talk button when close to a character or pickup, and F or tap an Act button to use the selected method. Number keys 1/2/3 select the method. Available methods are exactly: (1) “Rumor Setup,” requiring no weapon, quiet, usable near Mika, and producing a text-only/cinematic result where the rival leaves campus in tears; (2) “Prop Knife,” requiring pickup of a prop knife, non-graphic and represented by a shadow/cinematic cutscene, usable very close to Mika; and (3) “Fountain Push,” requiring both the player and Mika to be near the fountain and producing a dramatic splash cutscene. Do not depict graphic violence. Place a glowing prop-knife pickup on the lawn near coordinates corresponding to the right side of the fountain/crosswalk area; E picks it up and it disappears. Carrying it near Jun, the hall monitor, gradually increases suspicion, while suspicion slowly cools when away.

Create these six moving NPCs with the shown names/roles and routines: Aoi “Senpai” Mori, a shy, bashful, poetic male crush with dark blue hair and a unique slightly larger male model, positioned around the rear academy/courtyard route; Mika Rose, the rival with pink hair, popular/confident and flirty with Senpai, marked with a “Rival: Mika” label; Jun Hallwatch, a strict hall monitor with dark hair who patrols and notices the prop knife quickly; Emi Sketch, a dreamy art-club student with purple hair; Rin Dash, a competitive athlete with orange hair patrolling the outer track; and Sora Signal, a cyan-haired gossip who knows secrets and trades favors. Give each a looping patrol route. Talking to Senpai shows dialogue with choices to compliment him (score +5 and an affection message) or ask about Mika (revealing that Mika visits the fountain after class). Talking to Mika offers “Be sweet,” lowering suspicion by 3, or “Walk away.” Talking to other students shows their personality; the player can ask them to follow or trade gossip. Recruiting Emi, Rin, Sora, and other non-rival/non-Senpai students makes them follow behind the player, and the HUD follower count updates; trade gossip increases score by 3. Allow followers to be toggled off by talking to them again.

When the selected method is valid and used, run a roughly 1.8-second non-graphic camera cutscene focused on Mika with a centered overlay showing the method name and its explanatory text, then hide Mika/remove her from the scene. If no eligible witness is within the method’s witness radius, award 20 score and show that no witnesses saw anything. If a non-rival, non-Senpai student is close enough to witness it, award only 6 score, increase suspicion by 35 percentage points, and show a warning that someone saw something. Rumor Setup has a smaller witness radius than the other methods. If the method is invalid, show contextual messages: the prop knife must be picked up first; the player must get closer to Mika; or, for Fountain Push, closer to Mika and the fountain. Once Mika is gone, approaching Senpai triggers the ending dialogue: if suspicion is below 70%, he says the campus feels calmer and asks the player to walk home, leading to “Ending: Bashful Walk Home”; otherwise he says everyone is whispering and he is scared, leading to “Ending: Suspicious Silence.”

Use a polished HUD matching the screenshot: top-left rounded dark translucent title card reading “Heartlock Academy” with subtitle “Original stealth/social slice”; top-right rounded dark stats panel showing Method, Weapon (“none” or “Prop knife”), Followers, Suspicion as a percentage, and Score; a wide dark translucent mission/message bar near the upper middle reading initially “Find Senpai, learn personalities, and handle the rival quietly.” Show contextual interaction prompts near the bottom/center such as “E Talk to [name] · F use [method],” “E Pick up prop knife,” or “F use Fountain Method Spot.” On mobile, show a pink/purple circular virtual joystick at bottom-left and two large pink-to-purple gradient rounded buttons at bottom-right labeled “Talk” and “Act.” Include a dialogue panel with speaker, line, and choice buttons, plus click feedback sounds. Make world labels billboard toward the camera. Preserve the bright pastel, soft-shadow, low-poly social-stealth presentation and the non-graphic tone.
