Actually I wanted didn't made the hearts triggers because I wanted them to be felt like they have some weight and are a solid object and not just something you can touch and collect in passing. But I agree that at this point, the game is too challenging. I will update the game after the judging period for the jam ends.
Well, I don't have much knowledge about music but when I heard the song Lights Out, it just felt like evoking an emotion of a searching or longing in a modern world. But it's of course subjective. What I felt may be completely different from what you felt. But thanks for playing and the feedback.
