The game had good promise, which is really a bummer. Like someone else said, the game saves at "checkpoints" not where you actually are. I had completely finished in the bathroom and office, up to placing the gears to open the bedroom. Manually saved only to come back to have to use more energy to repeat everything after the kitchen. Probably 50+energy worth. The puzzles aren't logical at all. Circles are squares and somehow a clue with the date 2013.04.25 means enter 40251384?? Bummer.
