Save the Tiger

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 “Save the Tiger” as a kid-friendly 3D jungle runner/adventure. Use a third-person, behind-the-ranger camera looking down a long straight jungle path; the ranger automatically runs forward along the negative Z direction at a constant pace, while the camera smoothly follows from behind and slightly above. The scene should be stylized low-poly Three.js-like 3D: a dark green foggy jungle, deep green ground, a wide brown dirt path, warm directional sunlight, simple cone-shaped leafy trees with brown trunks lining both sides, and occasional hanging green vines. Keep the tone non-realistic and non-graphic.

The player is a small colorful ranger represented by a rounded capsule-shaped body, a simple toy-like yellow blaster, and a circular badge floating above their head. Before the first run, provide a setup overlay where the player must enter a name and choose one of three avatar badge designs: Leaf (green leaf), Sun (yellow sun), or River (blue waves). Show the chosen name in the HUD as “Ranger: [name]”. Persist the name, avatar, coins, purchased items, and equipped skin using browser local storage. Cosmetic ranger colors are available: default cyan body/yellow blaster, Sunset orange body/light blaster, and Ocean blue body/mint blaster.

Core controls and gameplay: A moves one lane left and D moves one lane right across three lanes at x positions approximately -3.2, 0, and 3.2. Space makes the ranger jump, with gravity and a single jump at a time. The ranger continuously advances, and the objective is to survive the route and reach the trapped tiger in the final clearing. Left mouse click fires a non-realistic tranquilizer shot using the centered on-screen crosshair; it can hit nearby poacher drones in front of the player. There is no gore: a successful hit gives 50 score, plays a chime, and changes the drone to a glowing blue stunned state for about two seconds. A drone that is not stunned can damage the player on contact.

Build the run as four sequential themed chapters, each about 100 world units long, with short full-screen text/narrator overlays between chapters. Chapter 1 is “Deforestation”: spawn brown horizontal fallen logs as hazards and occasional gold ring coins; explain that cutting forests removes tiger habitat. Chapter 2 is “Pollution”: spawn dark trash piles made from a gray bag and a small can, plus coins; explain that trash and toxins hurt animals and their food. Chapter 3 is “Wildfires”: spawn small orange-red emissive cone flames on dark bases, plus coins; explain that fires destroy habitats and advise jumping and lane switching. Chapter 4 is “Poaching”: spawn floating red toy-like rectangular poacher drones with a white/blue glowing eye, plus coins; explain that poachers seek profit and that tranquilizers make them harmlessly take a nap. Obstacles and coins should be distributed randomly among the three lanes with spacing, while the player has enough time to switch lanes or jump.

Gold ring coins float and rotate on the path. Collecting one when close adds 10 score and 1 persistent coin, plays a chime, and removes it. Logs, trash, fire, and active drones cause one-heart damage on contact if the player is near the ground; jumping can avoid them. After damage, grant about 1.1 seconds of invulnerability and visibly blink the player. Start with 3 hearts, or 4 if the Extra Heart shop upgrade has been purchased. If all hearts are lost, pause with a full-screen lose overlay saying the ranger did not make it and offering Restart.

The HUD remains over the 3D view. In the upper-left show pink heart icons (with empty/disabled hearts after damage), “Score: 0”, “Coins: 0”, and the ranger name. In the upper-right show a small control hint such as “A/D: lanes • Space: jump • Click: tranquilize • B: shop • M: music • V: voice • R: restart”, plus a Shop (B) button. Keep a white circular crosshair with short horizontal and vertical marks at screen center. The initial/start overlay has the title “Save the Tiger”, subtitle “An adventure through the jungle’s biggest dangers.”, a jungle-rescue explanation, a Begin/Start Adventure button, Voice: On and Music: On toggles, and a note that clicking enables browser audio.

Implement full-screen text cutscenes for the intro, chapter transitions, win, and lose states, with optional browser speechSynthesis narration controlled by the Voice toggle. The intro tells the player they are a jungle ranger, should collect coins and dodge hazards, and can tranquilize drones. Chapter cards display each chapter name and educational explanation. At the end, when the player reaches roughly Z=-455, show a simple stylized tiger in the clearing: orange capsule body, orange head, and a dark stripe-like ring detail. Display a win overlay saying “You made it! The tiger is safe.” and award +5 persistent coins for rescuing it, with a Play Again option.

Add a pauseable shop opened with B or the HUD button. The shop overlay shows the coin total and sells one-time Extra Heart for 12 coins (“Start runs with 4 hearts instead of 3”), Sunset skin for 18 coins, and Ocean skin for 18 coins. Purchased skins can be equipped, and include a Change ranger option that returns to avatar/name setup. Continue or Escape closes the shop and resumes the run. R restarts the game; M toggles looping jungle music; V toggles narrator voice. Include simple jungle adventure music plus shooting and collecting/win chime sound effects, with audio safely unlocked after a user gesture. Use responsive overlay styling: translucent dark green/black panel, pale text, green primary buttons, rounded controls, and the 3D jungle visible behind the UI.
