Thanks! Could you tell us where exactly the black screen/music looping occurred (after the scene faded to black after the final CG of Beth, or earlier)? Did the credits never appear at all?
Ahh, okay! If you should have spare time at some point to skip through again with similar choices, we made a new build that may or may not fix it. If you get stuck again, please let us know.
