Seriously buggy - Do NOT buy
The first time through, I progressed to a point where I was supposed to climb the ship, and I got locked up (That is the protagonist wouldn't move in any direction). When I re-started, she refused (vocally) to go in that area of the ship again.
I started all over. This time I got stopped, repeatedly, in an area I had passed through smoothly the first time. Same deal - once stopped I could not get her to move in any direction, even when reloading from an earlier save and moving to the trouble point.
OK - that's enough, unload the game and into the wastebasket it goes!
Too bad, I really like the occasional adventure game.
