Keep in mind that I've only watched the first 3 episodes. I don't know if they get better or worse or stay the same.
The concept of the show is really cool, and it's quite enjoyable to watch. I love the characters and their designs, and their personalities are pretty well developed. The animation is also really high quality and nice looking for an indie show.
A common criticism I've seen is of the humor. I personally like meta humor, but I do think they went a little overboard with it.
My main problem with this show is the pacing, which I've seen many other people talk about. Everything happens so fast that had to rewatch the episodes several times to fully grasp everything that happened. Some character arcs happen so fast that I really have to read into the episode to notice them. The characters swap sides so much that I have trouble figuring out whose side they're on sometimes. I have trouble figuring out the main motive of the characters, and whats supposed to be the problem at the moment.
I think this could've been avoided by either making the episodes longer, or making more episodes, but I understand that would take much more time and money.
All and all, I do think it's worth watching, but only if you are really focused and prepared to comprehend things very quickly.
