I bought the game yesterday (missed the sale by some hours) and I'm IMMENSELY enjoying it.
I feel like a blind Ripley on the Nostromo...I'm in chapter 9 now and I had a real blast.
Are there any similar experiences in the AppStore?
I do not like the Papa Sangre setting, so I unfortunately ruled it out.
Check out Blindspace or Blindscape (I forget the name; may be two words, not one) I think it's still free. There's an arcade all-audio game named Audio Invaders (if it's still in the store...sigh). Might want to check out Hiversaires, a cool game with superb audio and minimalistic graphics. I think it has a review here.
