The secrets were my favorite part, it made it me feel like a kid again. There are parts of the game that you'll never see if you don't explore off the easy path. I kind of wish they told you ahead of time that those areas exist, though, even if they don't tell you how to get to them. I'm so accustomed to modern games having one path from start to finish, that I didn't bother exploring until I happened to read a comment talking about the secret areas. I probably doubled my amount of play time after I started exploring, and trying to access all the optional areas. Unfortunately, some areas seem to only be reachable if you are lucky enough to get certain wands, or the procedurally generated terrain is in a favorable layout.
