The core mechanic here is really fun, and was executed very well. I especially love that you made the battery level visible on the main character. Also the sheer panic I felt after killing the first enemy only to realize I had to run and find more batteries when I had foolishly run into the crowd of enemies. It took me like 5 tries to win. Overall great work! I do kinda wish the game had some sounds but even without it was very fun.
