One Eye Open by Colin Sandel and Carolyn VanEseltine

Had you known the bloody history of Corona Labs, you would never have signed up as a test subject. But now, plunged into that history, surrounded by the damned and the dying, you must find the truth. Perhaps you will even survive it.

Even though the next step was oftentimes quite far from obvious, the nice plot and the genuine clues (HINT) compensated for it. I agree with those before me: EXITS comes in handy as descriptions do not always mention them.

A game of genuine quality.

So much to like: The nightmarish mood, the attention to detail in the writing about the settings and staff of the facility (past, present and future), the CONCENTRATE command....

Well worth a few hours of any horror fan's time.

Too complicated for me. I don't really know how I'm supposed to answer what I see on the card Dr. Ephart is holding up when all I can do is "concentrate" on it.

Finally a game where I can literally explore everything. this made me look in places other games taught me were stupid and I love the chilling detail. I haven't finished but I love it so much man.

Give my 100% seal of approval for this masterpiece! Great storyline if you look deep enough and are a good searcher in text based games!

This game is very imaginative and suspenseful. Even though there is gore, it's not the main sense of unease and is more there to help steer you in the right path. The plot and writing are well thought out and I appreciate how much effort that must have been put into creating this.

A great game with lots to explore, great twists and turns, and a wonderfully spooky environment for play. If you haven't played it before, give it a whirl. It isn't quite like any other IF I've ever played. Scary, but not too nasty- like all good horror, it relies on suspense as opposed to pointless gore.

I really loved this game! There's so much going on and while it was tricky to begin with, once I paid attention and saw I could List Verbs and even get Hints if I got really stuck it was great! Especially because this is one of the first text adventures I've played in a couple decades so I was really rusty on how to play them. A fantastic game and one that makes you keep thinking afterwards.
