Okay, I've been trying to beat this for hours.
So far I've figured out that the 6 main paintings are missing something (a sword, a crown, a walking stick, etc.) and you have to find them and place them in the painting. Then in the main "red hall" you have to flip the switched to the completed paintings room.
I also found out that you have to bribe a squirrel for the sword (with acorns) and take a picture in the smaller gallery and use the 'contrast' button to read a hidden message.
Now I don't know what to do with the last two paintings that are unfinished.
Has anyone played it?? http://www.minijuegos.com/juegos/html/index.php?id=2794
Okay, I just found the last two pieces to add the puzzle and a lazer comes out of the center switch. Then you go to the gallery and flip the switch that looks like asoccer ball. A stairwell opens up and you go down the basement. I got into door two and got a red box with a shotgun shell in it. But I can't figure out the passcode to door 3. It has to do with the pictures I'm sure. But I can figure them out.
