The graphics are simple, but the game manages to convey the atmosphere quite well, both through sound and the environment. I really liked how the guards were done. The captcha was a nice touch.
It seems to be impossible to beat the first location on the first try, the battery charge runs out way before you're able to explore every available door, but I managed to collect enough info so that on the 3rd try I could run between points of interest and collect extra batteries along the way.
I didn't quite understand what happened in the 2nd location: once I've started absorbing the battery, there were 2 bars and a point that was on a bar, but then detached and fell off somewhere beyond the screen. Was that a direction indicator? I tried following it, but then the game started lagging and I died.
Other confusing moments:
1. When sprinting, the robot leaves behind a trail - is that the leaking charge, or a smell trail?
2. It's unclear what doors can be opened
3. The wire connection minigame doesn't work if you try to connect wires from right to left
