What a sweet game (no pun intended, haha) . Only problem i faced was with the circles on the floor puzzle. I couldn't grasp the correct hints so I went with trial and error method. That is a lack on my part. Great game!! The puzzles were of just the right difficulty and the conclusion was even better than I thought. A total surprise.
I love these little surprise endings that you include, it makes the story richer. The best part is that the element of surprise is not jarring. It ties well into the story and in fact, even enhances it.
