I actually finished it a while ago. And I agree on most points with r.u.s.s. and TotalAnarchy, but I didn't have any problems at all with load times.
It did however freeze on me a few times, the first time I had to play the entire beginning again which was fairly annoying.
The voice-over didn't annoy me all that much, although at some points the words were really weirdly pronounced.
All in all I enjoyed the game very much and I was very happy to see that there is still people out there who can be bothered to make an old fashioned point and click game.
