Unity Mini Games

13 classic mini games I developed in Unity from scratch, designed as a hands-on reference for game development students learning core mechanics, algorithms, and data structures.

Objective

Provide a self-contained collection of well-known game implementations that cover the fundamental patterns encountered in game development exams and entry-level projects. Each game focuses on the core mechanic rather than visual polish, making the underlying logic easy to study and reproduce. The repository is intended as a rebuild-it-yourself exercise: attempt each game from scratch and use this repo as a reference when stuck.

Limitations & Future Work

The focus is on core mechanics rather than visual polish. Possible extensions include:

• Visual overhaul with consistent art style across all 13 games
• High-score persistence using PlayerPrefs or JSON serialisation
• Difficulty scaling (adaptive enemy speed, shrinking paddles, faster drops)
• Mobile touch input for deployment on Android / iOS
• Menu hub scene with game selection and progress tracking
• Additional games (Pac-Man, Connect Four, 2048, Sudoku)
