Really enjoyed the mechanics and the graphics were so pleasing to look at. I really liked the batteries little waddle as it was so cute. Overall I have no problems with gameplay. However I would add some background music (even if it's quiet) and some particles whilst the battery walks. I had fun in this puzzle adventure!
