Mute buttons did not work.
Another great sequel, however this one presented a few issues. Too many items, or red herrings as others like to call them. The ability to sell and re-purchase is an improvement on the last game's money system, however the ability to sell necessary quest items and needing to purchase them back for DOUBLE makes it easy to get yourself stuck and unable to progress and thus needing to start over. Buyback for exactly what you sold it for would solve the issue, though personally I prefer the way you addressed this in daymare 4, which I'll talk about in that game's review.
The other issue I feel this game had was a confusing map layout. Sudden changes in angle or direction (or at least that is what it seemed like) at crucial junctures served only to disorient and frustrate me.
