Okay, it's quite a clever idea! I loved automating the batteries, nice balancing too! :D
Like the comments before me, I had some issues with the screen size, but it didn't hinder me from having fun. I think this game and the idea definitely have some potential for a small incremental game release on Steam or Itch. It just needs some polish in the graphics and accessibility department (maybe include an option where you don't have to click, but instead hold down the mouse? Some people have difficulties clicking non-stop).
Do you want to follow that direction, or was it just a little prototype for the jam?
Congrats on the entry! <3
