It is never a good sign to come across a typo in the very first sentence: a good old proofreading would be useful here. I liked the out-of-nowhere, nightmarish opening though ("you're running..."). It is a promising idea that needs to be elaborated on. Quite much.
It an intriguing take on CYOA. The precision of the story-telling is impressive (with you playing the "human-like" AI and everything), as is the high number or well-thought-trough results. One thing though: as it is a human-like AI with human-like thinking, it would have been more realistic for it to be able to turn back to a planet already scanned.
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.
