Opinion & Informal
Art: 7/10 It was good and detailed.
Animation: 7/10 Mostly to show the skill of the animator in my opinion, but it was very fluid. May make some dizzy.
Plot: 6/10 There's an actual plot here but it wasn't that interesting.
Development: 6/10 There's actual development, but hard to decipher any deeper meaning at all aside from what the synopsis tells us.
Music: 5/10 There's actual music, but I didn't particularly like it and couldn't judge its appropriateness.
Overall: 6/10 It was fine. Most notable for the art and animation. There is a very simple but not fleshed out plot. Music was not memorable or didn't feel too engaging to the story.
