There's a black screen at start but it's just a very big game so takes several minutes to load- I left it and after a few mins the game started.
The game is interesting with nice atmosphere and the graphics are really good, but it's still pretty buggy and even on lowest settings it's jerky. If you die you have to start all over again, the game can be impossible to win if you do things in the wrong order, and you spend much time guessing what you're supposed to be doing.
Still more interesting than most efforts though.
