Well, Skot, you've consumed a few of my hours, so far. I've played the main game and am now working on those Easter eggs. I still need a few. I've replayed a few times to try and see if they were hidden there, but I'm still not sure what to do. I need a few more, the Tree, Ghost, 1124 and 11:11. I'll figure it out, eventually.
The game itself was very immersive, as your description would suggest. I needed a bit of help on a few of them, my first time around. While the hints worked for most, I could not, for the life of me, understand the spider key. I had to look that one up. Creative. The puzzles were generally doable, even if I had to resort to hints, a few times.
My first play through took about an hour or so. While some may say that isn't worth the price, I quite enjoyed the story itself. Predictable, at times. Even so, the introspective aspect was something that really interested me. I enjoyed it, at least. In addition, while I did only spend an hour the first time, I've replayed several times. Right now, I think I've spent a total of four or five hours on the game. Well worth the price, I would say. Thanks for the game.
Tl;dr: Challenging but doable puzzles, interesting if a bit short and predictable plot. Recommended to anyone who likes text-based games with good plot. Not recommended to someone who can't stand puzzlers and/or can't bear to spend money on games.
