It wasn't over and over, but it said a lot the phrase "Cut cut cut cut, try again". And happened to say it 2 or 3 times consecutively at one of the last levels (died a lot there :P).
About the sound lacking, as I say in the comment, I don't know what else I would add, it just felt really "plane" for some reason. Background sound is already in it and fits ok. I think the boxes could use some sound on them (they don't sound I think), and also the portal sounds really low in my opinion.
