Realms of the Haunting Hints

The five hands puzzle can be won by pushing the top right hand first and then the bottom far left hand will open up the panel to the wall with the glowing walls. Save the game prior to trying this so that if you make a mistake you can restore to a time before you started pushing the hand panels.
The fireball platform room requires that you avoid the floor switches which cause the fireballs to shoot. Jumping over the floor switches at the corners allows you to avoid them. Shooting the four floating mirrors one at a time will deactivate the lights and allow entry into the alcove directly across from the entrance. Notice that all mirrors but one are protected by a force field. Breaking one mirror removes the force field from the next mirror that you can now destroy. Once all four mirrors are broken, enter the alcove, and jump up on the pillar in the corner of the alcove to lower it, which will allow you access to a dial in the other room by removing the forcefield.
