I really struggled to understand what was being said most of the time as the background music really competed with your audio, so it was a good move including subtitles.
I tend to see a lot of animations that use characters like yours, and they're generally done so the animator doesn't need to put the effort in by drawing human characters. I mean, the animation had nothing to do with them being boxes or paper, so it just seems a tad lazy.
Visuals were nice. Dialogue was utter jibberish but I had a laugh.
