Loved the art style and audio for this one!
It was a bit unclear where I had to go and how to interact, but I eventually found out through trial and error (I thought I would have needed to place the battery for it to charge the elevator). Adding some text in the tutorial level would probably help to clear things up.
It also feels like the battery drain can be a bit too punishing at times. At first I didn't know why it was draining so fast as there isn't much feedback showing you that obstacles take away your charge. I kept needing to reopen the game to restart the level upon every death as well.
Overall though, I really like where this game is going. Keep up the good work!
