In short: Afaik this was
Philly_Games's first game, he was still experimenting and learning and I'm pretty sure that I've read here somewhere that there are definitely some shots in here he isn't particularly proud of... ...but imho this is still worth it for the story... ...and it definitely gets better the further you go.
If you can't get over it, though, just leave it and have a look at
City of Broken Dreamers instead - that's on an entirely different level, still a great story, but you won't stop ogling, I promise.
