Animation makes use of crude but legible shapes, but moreso I like the pacing. After the reveal and near disaster in the office building you see that the threat is real. Also the stitch foreshadowing in the beginning that you get to see when you watch it again.

At around 1:00 I started to get into it. The decrescendo in the middle felt short. The ping pong pops (I'm not sure what to call them) volume gave them most of my attention in the second half. oldskool was an excellent tag choice.
