Glad you had fun!
Also, sorry, the darkness wasn't meant to be permanent. The bug was only just found after the grace period. I think it happens when you revisit the room where the trigger for the darkness is. And resetting seems the only way to get rid of it right now. We're just hoping no one else strays and ends up backtracking that far back on the way home. ;>m>
But thanks for enjoying our game anyway!
