Took me a few mins to download last night and had no probs with that (using firefox for downoads as it is better at handling large files than IE by the way).
Played the game up to the point when I went into the lift a second time and got stuck, the lift would not go anywhere then.
Very, very, nicely made game I thought, too scary for the faint of heart or younger players. Atmosphere was just right for this type of game and aided by the sound clips.
Really any bugs are probably just due to FPSC, the see-through door springs to mind which is locked but you can walk through and fall to your death.
Good story with a twist. I think you should consider cleaning up the rough edges and then selling the game, should make you a few dollars
