Open the Door

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.

Create a minimalist single-scene 3D interaction game titled “Open the Door.” Use a Three.js-style perspective camera in a fixed, slightly elevated three-quarter view aimed at a doorway on a large plain gray stone/concrete wall. The environment should be sparse: a broad blue-gray stone floor, a dark navy background/sky, soft fog, and subdued realistic lighting with warm directional highlights, cool fill light, ambient shadows, and shadows cast by the doorway and character. Place a square doorway frame against the back wall and a hinged rotating door in it. Add a small metallic silver handle on the front of the door; make the handle a clickable raycast target. Add a simple blocky humanoid character standing to the left of the doorway, facing toward it, with an idle animation. Keep the camera fixed; there is no player movement, combat, inventory, timer, score, lives, or other level progression.

The only gameplay action is toggling the door. When the player taps/clicks the handle, or presses the prominent bottom-right “Open handle” button, animate the door smoothly over about 0.72 seconds with an ease-in/ease-out curve, rotating it around its hinge to roughly 0.52π radians open. Move/rotate the handle with the door so it stays attached. The action should toggle: if the door is already open, the same interaction closes it. While the door is animating, ignore further triggers. When triggered, briefly play the character’s “interact-right” animation if available, then return to its idle animation when the door movement finishes.

Overlay a simple HUD over the full-screen canvas: at the top-left show bold white uppercase text “OPEN THE DOOR” with slight letter spacing and a dark shadow; at the bottom center show a dark translucent pill-shaped hint reading “Tap the vertical handle or press Open”; at the bottom-right show a gold/yellow rounded rectangular button labeled “Open handle” in bold dark text, with a subtle shadow and a pressed-state effect. Make the canvas fill the viewport, prevent scrolling, support pointer/touch input, and preserve the clean, sparse presentation. Use low-detail Kenney-like building and blocky-character assets or equivalent geometry, with the doorway/wall in muted gray and the floor in blue-gray.
