Giving a low review because the game seems pretty broken right now, but the mechanics work alright! There aren't any colliders on buildings / walls so you can just walk onto them, and once you enter the subway you can't leave, plus there isn't really any actual gameplay at the moment. I'd also recommend using higher quality textures, as they're very pixelated right now.
That being said, good work getting the gameplay to function, and you'll probably be able to improve this significantly in the future! Good luck :D
