Project Overview

Tetris Sudocu was developed as a technical assignment for a Unity Developer position. The project combines classic block-fitting gameplay with Sudoku-style grid clearance, requiring clean architecture, testable logic, and polished UX.

Technical Highlights

Dependency Injection & Reactive Flow: Leveraged Zenject for loose coupling and R3 (the modern C# reactive framework) to publish board state changes without tightly coupled callbacks.
Custom Editor Tooling: Implemented an inspector-based 5x5 matrix editor allowing designers to create and edit custom figures directly in Unity without modifying code.
