K×Drop!!

Spoilers Beware:

Sound: I approve of the choice of music, uproarious bangs add suspense to the situation. There are realistic sounds of objects breaking and directional cues of audio.
Overall a 6 to keep you on the edge of your seat

Art: The landscape of the mall seems to be appealing to the eye, with the way light reflects on objects and looks bright in a night setting. The shadows of dark rooms do make it hard to see. I also like the art style the way the characters are drawn. It reminds me of how characters are drawn in Kill la Kill. The score is ... a 7.5, but I'll round it to an 8.

Character: Endo runs around the mall and is freaked out easily. The score is a 4

Story: Endo, the security guard, chased an unknown intruder in the mall(public property) he works at later to find out it was a cat. He accidentally punched his partner in a panic, thinking the person behind the door is the culprit of the chaos. But it is revealed there is actually someone in hiding. Nothing out of the ordinary. My score is a 5

My final score is a 6 considering this a self-independent animation and is fine for 5 minutes.
