As I look into my game concept and since I know that I wanted to make it an educational game, I went to into how to make a circuit work. Since it is aimed for kids, I was thinking of bright and neon colours to capture the attention.
Additionally, I look into possible environments as suggested by Justin. On this page, once the player is able to complete the circuit at the various stages, a robot will be constructed and the trophy room is where they'll be placed at. The robots would be animated, showing their personality as they are displayed.
