The constantly shifting background on the game page is distracting.

I think the concept is interesting and the story had me for a bit, but after a while I started losing interest. You've got a lot of long sections of writing that only really serve to keep up the tone. This wouldn't be a problem if each a bit more lore, as it is, it just feels like extra reading. I think if you work more on this, it'd be a good idea to go back through your writing and see where you can fit in more inferences about the actual life-style of the player character and the specific ways in which the city is horrible while still keeping each section about the same length. The additional options you mentioned on the game page are a good idea as well.

If there's any way you can fit in an option to make the text go faster, that would be a good idea too. In my experience most people who are old enough to be reading this sort of material can read faster than your text appeared.
