I enjoy the humor in the game. However, I have stepped aside from _playing_ the game to post regarding this topic. Hopefully you will find it constructive feedback.
I will simply say that a specific set of 'narrations' is actually hindering my enjoyment of the game, which makes me sad panda. And I suggest a solution...
However well a game is designed and written, people are going to try to do the "wrong" thing, and often. It is the responses to these innocent missteps that can be received as grating, particularly since the player is already disappointed that their action has failed.
I suggest adding a game option, similar to "Short narrations", that would replace all witty fail responses ("Guards! Guards! ...", "Have you gone CRAZY! ...", "Graham is not THAT generous! ...", etc), with simple fail responses ("uh-uh", or "no"). Such responses have proven effective in other adventure games.
For myself, this option will turn the tide, so that I can once again look forward to Amy's beautiful narration with anticipation, rather than disquiet.
Thank you for listening.
