These are really addictive.. Helps to calm my nerves Great work.
Two good points. First, the gem slots are visible when exploring the rooms. This has shortened the time to put the gems back after finding them. Second, there are removable parts which reveal a hidden item. It's a nice addition to the game.
Nevertheless, I couldn't find a screwdriver until I read the walk through comments. It should be placed against a contrasting background instead of reflecting water. :/
