Are there any gaps in the world map or is it a solid 48x30 block?

The completionist in me needs to know before I start checking every wall in the game for a nonexistent room.

Also, are there any areas that aren't on that map?

It's a solid block, and there are also rooms in the game that don't show up in it. There is a high probability the completionist in you will never be sated.

Lol sergiocornaga, thats an understatement!

Yeah, there are so many secrets in this game its crazy.

And really, it goes crazy far. Think about secrets at locations you would not expect them to be, and secrets in secrets. Most of them are also hard to find, but when you do, a great reward for finding them! (sometimes a complete story/quest.)

Secrets in Knytt Underground are designed a bit like the ones in the first Zelda game (bomb that tree) and have no indication of being there. I'm hoping they will spread by word of moth.

Nifflas, "word of moth" was the best typo I have seen this year and I curse you for fixing it,

I'll put the error back

Besides, if the secrets could spread by moth, that'd be AWESOME!

I think it's 50x30, not 48x30. However I still don't know how to get to the last two columns... I had couple ideas, but they were wrong.

It's just 48. Outside is just a margin. The reason the margin is bigger is that the aspect ratio of the game changed at one point.

Why would you tell me that
I've been vigorously trying to pass the surface :3
to no avail, of course...
