This is not a bug per se, but you can seemingly zoom out infinitely. I was looking to see if a secret area was out there while zoomed out, I spent about half a minute just zooming out to see how far it would go, then had to spend another half to zoom back in. Probably should put a zoom out limit on that, unless you're going to add something out there, which I think would be nice for a sneaky ending. Maybe an "escape the loop" ending that's way out there somewhere?
