Oh! I am happy to see that all your ideas have become a reality. This game has been carefully conceived and designed, with unified coordination in terms of UI. It is excellent in terms of color and button feedback effects. It is worth noting that you used yellow on the start button and provided green feedback, while using red feedback on the reset button! This is to distinguish the different functions of the buttons, and you also added a jump button, which is really innovative. I think this is a good gray box design worth learning from.
