I played it 3 times, but I don't have a slightest idea what the goal or objective is :C I'm too dumb :(
Good Stuff: environment is very nice, with cool pixelated look.
Bad stuff: picking batteries is super difficult, sometimes it gets picked up, usually it isn't. No clear goal of the game. Battery runs out waaaaay to fast, it's impossible to even look around and catch your bearings
