Really great looking!
In the area right after the tutorial there is a 3 light door:
This can be opened with only 1 battery:
I'm not sure if that's supposed to happen. I thought I needed 3 batteries to open 3 light doors.
The battery in that room can be gotten although it took a lot of attempts. Those middle platforms are really tricky.
Before back-tracking to that 3 light door I got stuck. I couldn't seem to make it past the room of many sweeping cameras. Once I did get that 2nd battery I could open a door (a level with palm trees and a battery) and I've been making progress from then on.
I do seem to keep ending up in places I can't proceed but the tool popups indicate that I should. I've reached the room with a battery and the tooltip is telling me about that jammer ball, but I only have 3 batteries. Perhaps that's all by design. Just a little strange that it took a lot to get that far to just to not be able to get the battery in the room (or maybe I've just not figured it out).
It is a really clever mechanic being able to kill the robots to recharge your own battery. I've have had quite a few "Ah-ha!" moments figuring some things out.
The robot's laser being able to follow/track you into the next room made for some occasional frustration.
