Paradox city

This must be the story of paradox city with some puzzles. I didn't end it yet.
You're little creature who can be in superposition like quantum particle. And you're exploring the city of paradoxes. A long-long time ago some people believed that our world not as simple as we get used to, they found some interesting things - paradoxes. They used it to build the Paradox city, and it was gorgeous town with cool technologies and endless chocolate. But as always, something went wrong, they confused in their own paradoxes, made wrong calculations and opened little black hole in the centre of city. It was a disaster, a lot of people died, a lot of left city forever, cause black hole, even small, could make many troubles. All centre was destroyed, and even now it gravitating to the black hole, so the city turned into the form of a spiral.
