I thought the writing was superb, the characters felt very well developed and funny for something so short. The jokes, one-liners and comedic timing was perfect!
I thought the voice acting was good, the quality of the voice recordings as far as "sound quality/mastering" could have been a bit better.
Also, in the future try to avoid copyrighted songs, they can cause troubles down the road. Not to self-promote but Newgrounds has a great assortment of talented artists and songs in the audio portal ranging from Rock to Classical to Piano Bar.
Overall, very well done, I look forward to the next one
