It's alright.
.:Animation:.
The animation was rather smooth. No blockyness, kept a constant speed, 5/5.
~
.:Art:.
The art isn't too great, then again, this is a stick. For a stick, there isn't always much to expect, just that there is some significant use of colors. This area was ok. However, there was no background. 2/5.

.:Plot:.
The plot was good, kept me in through the whole thing, and put me in suspense. To see what happens next, I'm going to watch the next part(s). Wasn't too boring, wasn't too slow, wasn't too fast. 4/5.

.:Audio:.
Here's where the criticism comes in. There's absolutely no sound in the beginning, but once they start to fight off a lot of people (pretty much when the giant comes), sound effects kick in. Kinda seems lazy. You were able to put in sounds, just not for the whole thing. However, when there was audio, it was pretty decent. 2/5.

.:Overall:.
The animation and plot were great, the art needed some work, as well as the audio, especially.
