Wow... sadly this type of point and click adventure game is a thing of the past, but this one is better in its short little story than a lot of the full length types ever were. Great game with a very creepy atmosphere.
Excellent puzzle game concept, but there are some severe problems. One, no save feature. Two, there are simply not enough tools available to you to win. If you had a few available by default, like a few color and symbol switchers every round, that would be a huge improvement. You need to take some of the luck out of the game otherwise it's impossible.
