I didn't know about the spinning, and never figured it out, so I guess it's not obvious. I might've understood it if I could see, but I didn't.
>how do you suggest i deal with the camera
I don't think zooming's bad in general, but the pixels act weird when you zoom in and out, and it's really noticeable, even more so when you have text - it affects text on the level a lot. That's what made it noticeable and not pleasant to the eyes. Maybe it's a problem with the shader - it seems to me like you're trying to rescale the drawn scene to still be pixel perfect. Or at least that's my first guess.
