Can you elaborate? Is it the lack of sound effects, the unforgiving collider, the messy shaking, the lack of camera movement?

Sound certainly. For the most part though, I didn't really know when I was shaking the battery and I wasn't clear where I could put the battery? Granted normally, that would be done with coloration highlighting the node where it goes but with black and white, that is a challenge. That was the main thing.
