Crocodracula: What Happened to Calvin

This was a fun little game, but I felt like I might have been missing some of the puzzles (other than the sheriff's crossword). I don't know if I'm just not able to figure it out, or if the puzzles aren't there in the first place. I thought the idea was cool, I mean, a game about a monster called Crocodracula? What's not to love? I did kind of wish the playable characters had a little more variation between them, but I can see why that would be a huge amount of work.
