I started the game and find myself enjoying it. I noticed one thing in the first area, Gomez Hometown, two rooms (see attachment) still have a question mark beside it on my map as soon as a can look at it, despite me already having been there and finding the two secrets, the map and the treasure.

To my eye there is no other secret in those two rooms, is there? Another bug maybe?

This should solve your problem:

Thanks, I was thinking that too. I'll give it some time then, more than willing to do that. :)
