The visual style is probably the shows strongest point and proves that not everything needs/should be made in the "generic anime" style. But Acca has a good story to tell too, albeit a bit confusing for the 1st half and Acca also has excellent fujoshi bai... I mean characters.

The ending was a bit unsatisfying, but probably better that it didn't go the other way.

A bit confusing but good conspiracy story.

Great animation, not much movement but the style stands out and will be remembered for a long time.

Sound is great, lot's of jazzy/groovy tracks.

Characters are great, most don't get much screen time, even some important ones, but such is life.

BONUS time:

Acca 13, so having 12 episodes instead of 13 was a reference to the state of things at the end huh.

Damn fujoshi bait at the end, Jean and Mauve would have made a good couple, but no gotta pair him with the child hood friend Niino.
