Hi Hejie! I think the art assets you've created are exceptional, especially your deep thought and commitment when tackling the challenges of UI design. You've managed to focus not only on functionality but also on ensuring that the design aesthetically aligns with the overall game. Considering your goal to avoid simplistic designs, have you thought about incorporating elements like gears, levers, or factory signs to enhance the game's theme? Perhaps adding more animations or visual cues could make the interface elements more intuitive and engaging, without detracting from the game's overall aesthetic. In summary, I truly appreciate and am grateful for the effort you've put into this team!
