Nice little game !
I found the game pretty hard, I wasn't able to reach more than 1min of survival even when running around non-stop. I think it would have been nice to have mechanics to refill the battery so that you can survive for longer.
Also, minor detail but I struggled with the controls of the character at first. Using standard WASD to move and the mouse to rotate the lamp would have been a bit more intuitive in my opinion.
Good work overall ! :)
