🎮 Add an Interactive Space-Themed Mini Game to the 404 Error Page

[krishkhinchi]

Description

Overview

Kepler already features a visually polished 404 "Object Not Found in Orbit" page that matches the Mission Control aesthetic. While informative, the page is static and offers little engagement for users who accidentally navigate to an invalid route.

Inspired by the Google Chrome Dino Game, this issue proposes adding a lightweight, browser-based space-themed endless runner that users can play directly on the 404 page while deciding where to navigate next.

Unlike the Chrome Dino game, this mini-game should be fully aligned with Kepler's futuristic space theme. The player should control a spacecraft navigating through orbital debris and space hazards, reinforcing the project's focus on satellite operations and space traffic management.

The game should load instantly, require no external dependencies beyond the existing frontend stack, and remain optional so it does not interfere with the primary purpose of the 404 page.

---

Objective

Create a small, polished, and performant mini-game that transforms the 404 page into an engaging experience while maintaining Kepler's Mission Control design language.

The game should be simple enough to understand within seconds but enjoyable enough to encourage exploration of the project.

---

Game Concept

Instead of a dinosaur running through a desert, the player controls a satellite, spacecraft, or autonomous orbital drone flying through space.

The objective is to survive as long as possible while avoiding obstacles.

The longer the player survives, the higher the score.

---

Theme

Everything should match Kepler's branding.

Examples include:

• Spacecraft instead of a dinosaur
• Space debris instead of cacti
• Asteroids and inactive satellites as obstacles
• Stars and nebulae as the background
• Orbit lines and telemetry effects
• Cyan HUD elements
• Mission Control UI styling
• Space-themed sound effects (optional)

The game should feel like a natural extension of the dashboard rather than an unrelated arcade game.

---

Gameplay Requirements

The game should include:

• Endless gameplay
• Increasing difficulty over time
• Score counter
• High score saved in Local Storage
• Pause and restart functionality
• Collision detection
• Smooth animations
• Responsive controls

Suggested controls:

• Space → Boost / Jump
• Arrow Up → Fly Up
• Arrow Down → Descend
• P → Pause
• R → Restart

Support both keyboard and touch controls for mobile devices.

---

Obstacles

Possible obstacles include:

• Space debris
• Defunct satellites
• Rocket bodies
• Asteroids
• Solar flare bursts
• Collision warning zones
• Broken satellite panels
• Orbital junk clusters

Obstacle speed should gradually increase as the score grows.

---

Collectibles (Optional)

To make gameplay more engaging, add collectible items such as:

• Satellite batteries
• AI cores
• Navigation beacons
• Fuel cells
• Data packets
• Shield boosts

Collecting these items can increase the score or provide temporary power-ups.

---

UI Requirements

Display a compact Mission Control HUD showing:

• Current Score
• High Score
• Distance Traveled
• Current Speed
• Game Status (Paused / Running / Game Over)

When the player crashes, display a modal with:

• Final Score
• High Score
• Play Again button
• Return to Dashboard button

---

Technical Requirements

• Build using React and TypeScript.
• Use HTML5 Canvas or lightweight SVG rendering.
• Avoid heavy game engines or unnecessary dependencies.
• Maintain smooth gameplay at 60 FPS.
• Store the high score in Local Storage.
• Keep the game modular and reusable.

• Achievement badges (e.g., "Debris Dodger", "Orbital Survivor").
• Hidden easter eggs referencing satellites, NASA, ISRO, ESA, or famous missions.
• "Warp Mode" power-up for temporary invincibility.

---

Acceptance Criteria

• A playable mini-game is integrated into the 404 page.
• The game matches Kepler's futuristic space theme.
