solved the puzzle about the eyes in the demon statue. By the way, you should get a look into that, dude. On my first atempt, the "key item" to solve this puzzle went through the wall, if you throw it. Thanks God I had a save few seconds before, lol.
So, my problem is, I gained access to the next room and solved the bolt puzzle. Also found the secret inside this room, but looks like I'm stuck there. Tried to re-do the bolt sequence but the door remains locked, preventing me to leave. Also, I assume we're suposed to find a key, since the nearby room needs one, but didn't find any
