Development of a 2D Text-Based Game in the Unity Engine Using the C# Language

The development of a 2D narrative game with a historical Chinese background presents both technical and cultural challenges. This work focuses on the creation of a functional software prototype set during the Tang dynasty, built on the principles of non-linear storytelling. The primary objective was not only to design an interactive dialogue system with identity selection and story branching, but also to explore how digital games can be used to convey cultural heritage. The technical implementation was carried out using the Unity game engine, the C# programming language, and the narrative tool Ink, which enabled the management of multilingual content and conditional dialogues. During development, specific attention was paid to the rendering of Chinese characters within Unity, which required the generation of a dynamic font atlas. The prototype’s functionality was validated through both quantitative and qualitative user testing. The final product combines interactive gameplay mechanics with narrative depth and cultural relevance.
