Throwing in my two cents and saying that a limited RO pool is fine. While I like romance, I’d actually prefer limited selections for a genre like this. It’s not like you should have many people you trust enough to jump into bed with, yeah?

Okay, so things that need to be addressed (and this is a lot of words, so bear with me. Most of it’s me prattling anyway):
Basic cleaning. You’ve got quite a few spots where there is no space between punctuation and the following sentence, and quite a few spots where there’s no line break between paragraphs. (I could-- and will gladly-- list them all if you want me to, but it’s a lengthy list and you might be fine with a suggestion to just check through your writing on the next pass.)
The next suggestion is to flesh things out. I know you’re just starting out, so obviously you don’t have everything written, but definitely go back through and add description to your scenes here. Motivations. There’s a nice rhythm to books and games if you pay attention, so that the description carries you and builds the mood and bam the next action scene is right at the peak of that. You won’t get that on your first draft, obviously, but it’s something you should keep in mind (and maybe study a bit of in similar works).
This is especially important when you have the sort of humor I think you’re going for here (dark, out-of-place crazy in a serious world). You need to set up the scene well if you’re going to make a satisfying punchline out of the secret handshake or the six pack.
One thing that bothers me is the throwaway line
Psychological Disorder: Sadistic.
Sadism is not actually a disorder, and wouldn’t be listed in a dossier as such (and I figure the dossier isn’t meant to be taken seriously anyway, but it doesn’t especially add to the scene anyway and was a little distracting.) You could also have fun with the dossier in different ways-- the likes/dislikes is a good place to go “Huh, I wonder how he figured THAT out.” Like maybe he likes a specific sub-species of mushroom or dislikes brown toupees or something. Also, give me more on this guy I’m killing. Build it up a bit before we end our first mission.
Also, I wasn’t a big fan of the abrupt “Give a codename” before I even had a sense of the character. Actually I had a brief moment where I was confused. “Codename? Does that mean my real name? Is this a permanent codename? A password? Why would numbers be specifically allowed/denied?” Most games on the site don’t ask for your name until part- or most- of the way through character generation. If you feel you have to ask that first, give me a bit more lead-in. Set the atmosphere for me.
I wish you the best with this game, by the way. I ramble way more about cons than pros when I write, but I promise I enjoyed the demo and look forward to seeing progress on it. It seems like it’ll be a lot of fun when it’s finished, if it follows the vision I think you have for it. 
And I always like clever-ing my way through a mission.
ETA: OH, also I like the stats screen and the way you have stats laid out. Seems like I can have a good time building my character.
