Thank you for your feedback.
You are right, the game is very quiet. We didn't have time to search for more sfx or fitting music. And that is why there aren't many custom responses when trying stuff that isn't necessary. That is something we can and will address after the voting period. (as well as the bug with the funnel, thanks for pointing that out)
In regard of the right click - that is a conscious decision we made. We prefer the two button interface like in the Broken Sword games, to give additional info when looking at things.
