I gave this game three stars after I first played it, intending to come back to it after reading a few reviews and giving it a few more plays, to see if I thought it really deserved four or whether I should stick with three. Unfortunately, additional attempts at play made me so frustrated that I almost ended up dropping my rating down to two. Even though I knew exactly what I needed to do to complete the first part, I ran out of time and died four times trying to get the timing to work; doubly frustrating as I'd managed it straight away the first time around, when I'd spent a lot more time wandering around the ship then. Resorting to the walkthrough, I found that the problem was caused by my having a mistaken mental picture of certain items.
Throughout the game, I didn't think the puzzles were particularly well-signalled; what I mean by that is that while they weren't difficult in the sense of needing a great amount of intellect, they were difficult in the sense of the circumstances around them not being very clearly explained. I also felt that the huge info-dump of made-up creation myth in the second part of the game was very off-putting.
Basically, I'm still annoyed with this game, and I'd be unlikely to recommend it to anyone else, particularly someone new to IF. I did like the fact that there were multiple solutions to some of the puzzles though.
