It seemed like no matter what I collect or avoid, nothing seems to change. I wasn't too bothered by this. To me, I can see some meaning behind it. The heart has a lock on it, implying that it's shielding itself and not trusting it's surroundings. Sends the message that if you aren't open to the love and care others offer, you'll never truly feel it. Though that might not have been the intention, it was a fun interpretation of the game I came up with.
