I did a play through of the game and it was pretty good! It basically shows the dark side of human emotions and addition.
Edit: For those who can't get the "Mirror Ending," follow these steps:
1. Open the game, close it, then reopen it
2.Ignore ALL notes except the days "CONSUME THE FLESH"
3. ONLY feed it during DAYS 1-5 and NOT feed it during Days 6-10
Thanks to scarybonz's video, I was able to get the Mirror Ending and I'll cite scarybonz in my video description.
