I don't think this level is actually "poor." More like "fair" or "just okay." Agree w/@ateeq that there's a lot of untapped potential in the concept.
@lukku Spoiler Try looking for something different among the balls. Spoiler Pay attention to a particular block that isn't round, and try to drag it.
@lukku - the majority of game shadows are calculated and set during the game creation (in the editor). Since what is inside the balls is completely surrounded, it is completely covered in shadow. Only localized shadows are recalculated during game play. Meaning that the major shadows created during game construction stay persistent throughout the game. Bots and water are exceptions as they do not take on shadows (for the most part).
