Is it permissible, for example, for me to add kinematicbody an and put a picture of it, or does the game have to be developed from scratch, meaning without a graphical interface with code only?
If you're using Godot, you can apply the engine's basic shapes to your kinematicbody, such as a circle or rectangle (or sphere / cube if you're working in 3d), and apply flat colors to them accordingly. You can use the GUI for your development, but the code in your scripts cannot be longer than 500 characters, and you're not permitted to import sprite sheets or assets. Does that all make sense?
