I found it interesting how many of the puzzles were really simple depending on what you were looking for. That's not to say that I didn't have any trouble in the first place. On the last puzzle, I actually knew the answer already, because it's usually around that point where the twist comes - my genre-savvy instincts kicked in at that moment - but I didn't put in the correct words, so I ended up loading the game in another tab to look for the necessary hints. I have to say that the secret ending was something I would never have looked for if I didn't know it existed. In a way, it's probably because I'm not trying to find anymore meaning than what's already fed to me.
Admittedly, the music was rather creepy, and it fit very well with the story. The way the text started to fade away after the correct answer was given was a really nice effect. For a small moment, you would think you hadn't typed in the correct answer when you really had. One thing that I really did find interesting was how all of the lines of text would travel all at once when you pressed the backspace button. It didn't give off a mechanical, yet lazy feel to it that an instant message display would. To me, that was just cool, and it was something I never saw before.
Anyway, this was a pretty pleasant experience, and I'm glad I got a chance to play this game. By the way, I don't suppose you're also a fan of the visual novel subgenre, too?
