The low-pixel-style game developed in Unity, with its easy-to-learn core gameplay, has successfully attracted new players and is especially suitable for children -- the simple gold collection loop is reinforced by audio-visual rewards (particle effects and pitch gradient sound effects), adding positive feedback. The characters are not overly animated, somewhat monotone, and there is room for technical improvement, such as insufficient boundary hints, but its modular design approach has demonstrated a solid foundation of the framework. It not only achieves the efficiency of the Unity toolchain, but also, as a student project, achieves a good balance between creative expression and technical practice, laying a sustainable expanded core architecture for future iterations to become a full casual game. ui design needs to be enhanced by using generic ICONS instead of text plus ICONS. But overall it's good
