Imagine that you are a homeless robot with an regular battery shortage. You travel, but do it not because of pleasure, but because fate requires it. Walking to different places, you find a lot of garbage bins, which are thrown out of batteries. They are enough to pave the way for 1 unit. But they leave quickly. You need to invest in each of the charges and passing obstacles to find a solar power station where you will live without needing anything. The game is during development levels.
