the gameplay does not meet the name or idea fractured and city are kind of different unless your implementing a city that is falling and fracutring.
a little to much flashes at the start still have the same color but maybe a little less flash triggers and could be also brighter flashes
could've made the design of the structure windows with yellow (lights) if he didn't already do this after the start but instead of all black and white you could do a little yellow light and it would stand out a lot as well
also the spikes could also be a more contrasting color like again a yellow or even a different color like red or orange instead of agian just all black and white
