If you guys figure it out the game makes since... I'll leave you with these hints;
1- and 2- Darkness reveal numbers.
3- Not above hint again. Highlighted numbers in two safes reveal combinations and combination order.
4- Check every book individually, and each page.
5- Compare letters to painting i.e. three rows of letters, 3 rows of flowers. Number of petals is number of button presses.
6- The picture points to a hidden compartment. Trust me, it's there. A lot of clicking was done to find it.
7- Note the number of sides and points of each shape in exit.jpg.
SPOILERS!!!!!!!!!!! Don't read unless you're seriously about to quit the game because you've been stuck for EVER!
