Cosmic Jump is a 2D endless runner game where players control an astronaut navigating through space, avoiding asteroids, and scoring points. The game offers an engaging and challenging experience, requiring quick reflexes and strategic jumping to achieve high scores.

The inspiration for Cosmic Jump came from classic endless runner games like Flappy Bird, combined with a space theme to add a unique twist. The goal was to create a simple yet addictive game that can be enjoyed by players of all ages.

As the developer of Cosmic Jump, I was responsible for the entire development process, including designing the game mechanics, implementing the code, creating the UI, and ensuring smooth gameplay. I also managed the integration of animations and sound effects to enhance the gaming experience.

Endless Runner: The astronaut moves forward automatically, and the player must navigate through randomly spawning asteroids.

Jump Mechanic: Pressing the space bar makes the astronaut jump, allowing it to avoid obstacles.

Score System: Points are earned by successfully passing asteroids without collision.

Game Over Condition: The game ends when the astronaut hits an asteroid or goes off-screen.

Challenge: Ensuring that asteroids spawn at random positions without making the game too difficult or too easy.

Solution: Implemented a random range for the Y-axis spawn position while maintaining a minimum gap between consecutive asteroids.

2. Collision Detection

Challenge: Accurately detecting collisions between the astronaut and asteroids to trigger the game-over state.

Solution: Used Unity's built-in 2D collision detection and adjusted colliders for precise detection.

3. Astronaut Rotation

Challenge: The astronaut was rotating uncontrollably when hitting obstacles or jumping.

Solution: Applied Unity's Rigidbody2D constraints to freeze the astronaut's rotation, ensuring it stays upright during gameplay.

4. Screen Boundaries

Challenge: Ensuring the game ends when the astronaut goes off-screen.

Solution: Implemented boundary detection in the Update method to check if the astronaut's position exceeds screen limits, triggering the game-over state if true.
