Oh wow!! This game looks fantastic! Just beautiful! I'm excited to see this because Myst is still my all-time favorite adventure game, and I haven't seen anything like it in a long time.
PS If the game's creator happens to poke his head into the forums, I wanted to say how happy I am for you that you were able to make this beautiful game! Being a Myst lover myself and a game-maker "wannabe", I am excited for you. Thanks for giving all of us something Myst-like to fall in love with again, and for getting me excited about learning to make games as well.
