I admit that I didn't really watch this series when it came out because honestly I didn't find much interest in it. However, after watching it, I must say that you have a lot of potential with this series. I would love to see this series continue, though there are some things that might need work.
The good things in this is that it's got a unique story, and even though the real story hasn't been revealed yet, I get the feeling it's gonna be good with everything set up here. Though honestly, I'm not sure how I feel about where the story's going since not much of the struggle has been set up yet other than them fighting the group of guys and Valas who I assume will become a major rival for the group. The art style is really nice, and the voices aren't bad even if there's some awkwardness in lines here and there.
As for areas that need improvement... This is a bit of a longer list. First problem is that the fight scenes are awkward. The movements don't look natural, and the fighting doesn't really flow that well in this one. Honestly, Valas seems like she just got knocked around because the plot demanded it, since she seemed like she should have no problem taking them all down but just couldn't. The plot also seems to be all over the place currently. Two episodes in, and the only thing close to a struggle with the heroes has been Valas who the group defeated. Honestly, there's been very little in terms of "plot" that has been introduced, and what little has been introduced has felt forced. A tree that shows up on infrared and them seeing an explosion while up at the tree? Seems a little too convenient. Also, the 'devices' they use are basically doing what cell phones do, except for perhaps the infrared vision. I really hope there's something unique there. For example, the guy using the map data really needs to understand that Google Maps exists. Honestly, I would rework the devices into something unique rather than just having them basically be smartphones. I get they were introduced years ago, but cell phones could still do what pretty much what they do now 3 years ago. And why exactly do their "phones" need infrared exactly? I would work on the story for future installments.
Another thing to work on is the humor. I am aware this was written two years ago, and I do understand that many people may find things like fart jokes funny, but honestly, your animation is better off without such childish humor. I can see some people's complaints about pretty sour humor, and I understand their opinions. If you are continuing this, I recommend being a little more classy with your humor. The dialogue, while not bad (aside from some of the humor), is really awkward and also needs more work.
As for the characters... They need some development bad. All I can tell about any of the characters is that Scoot is the main one. That's pretty much it. I don't know who anyone is, or what makes them unique. You took a step in the right direction in this one with giving each of them their own sorta unique style in the fight, but overall, the characters aren't developed enough to really make us care about them. The only real reason Valas stands out in this is that she's a female and an antagonist. The rest of the characters really don't stand out and none of them are unique enough to care about.
All in all, it's a pretty great series that I am curious to see where it goes if it is still being developed. I think with a little work, this can be a really great series if the problems are fixed.
