I like the level design, and the music is great. The mechanics are solid, and the art is simple but good. I do wish there was more, as I liked the level design, it was very creative. The animation at the end is also great. That being said, the usage of the them ended up feeling more like it made the game harder to control than anything else (although I assume that was the point, you really feel like your tethered). Since your using Unity, I would recommend making your game playable in browser. It's simple to do, just go into File-> Build Settings, and then change your platform to WebGL. There are several YouTube tutorials about it. Anyway, good entry! The lots of little details, like the two hands and the chain tethering the characters together, the police swinging their baton, the main menu-- they are all really good for the game.
