If you reject all predisposed knowledge of Undertale I think you will be left with one of the most beautiful experiences in contemporary gaming. The soundtrack is beautifully hand-crafted; It heightens the live experience and leaves you with memorable and remarkable tracks to listen back on outside of the game. The comedy is rich and also enhances the experience. Lastly, the freedom of choice in your actions, allowing you to dictate your environment and ending, is incredibly well done as you will see a reflection of your core values and beliefs come about. Why kill someone else just because they are indifferent to you? Do you value your own life?
