3 mentions Positive Neutral NegativeThe gameplay offers an open-ended, exploratory experience focused on discovering the universe's scale and structure, which may feel relaxing and rewarding for astronomy enthusiasts but aimless and lacking clear goals for those seeking traditional missions, narrative, or rewards.
