This game has a cool atmosphere and I like how you implemented the theme into this game. My main complaint is the level(s). I was able to understand how the mechanics work, but the first level is too hard to figure out the solution, so I ended up watching the video of the walkthrough (which ruined the fun for me).
Another thing I would like is more visual cues for before and after you clean the battery. Other than that, everything is pretty good. I like all of the sound effects you made, including when the sound pitch gets lower as the battery starts running out of energy. Looking forward to see what you make next!
