In fact, it was so much of a thrill that another feature some IF-purists might consider to be a drawback almost escaped my attention: in order to reach the winning ending, you'd need a few restarts -- a rather typical case of "learning from dying". Well, personally, I don't have anything against such a game device, but since modern IF-standards (whoever wrote 'em ;) generally don't countenance it I've had to mention it here.
Initially, I also was going to nag at the fact that the protagonisthadn't got a single chance to succeed in such a situation unless she was a clairvoyant, because a few strategic choices in the early stages of the game had to be made based on information she only would acquire later. However, a couple additional test playthroughs convinced me I had been wrong about it; there actually exists a way to victory that doesn't require the gift of foresight -- our PC merely has to be blessed with such abilities as ultra-fast acting and decision-making, an extraordinary analytical mind capable of calculating several moves ahead, and a memory as precise as that of a computer, all that combined with nerves of steel, as well as a thorough knowledge of the research complex. Of course, this all strains things a bit; still, there'snothing supernatural about the talents listed above. [In] my opinion, the very existence of such a "non-contradicting" way to victory represents another proof for the vast amount of thought and efforts that have flown into All Things Devours.
To sum up, this is a great game constructed around a very well thought-out and carefully implemented puzzle skeleton; the combination with the very original use of time-travelling effects makes it unique and therefore an absolute must to play."
