PS: On the subject of 4662 - Hungry by Android, I couldn't agree more.
As many on here will know, I tend to go a bit overboard with puzzles that require some artwork, and this one was no exception. I didn't just outline the raven, I coloured it in, gave it shade to simulate depth and movement and... well, I could go on but I won't bore you. Suffice to say, it was an excellent choice.
Another I can recommend is 4678 - Bleak Expectations by Mira.
