Noir Syndrome Message Board  

I think that options to change the number of lockpicks, bullets, and money would be good for this game.
Invulnerability might be hard to do, because Noir Syndrome kills you in one hit, and if you have loads of bullets, then death isn't a huge concern.

I don't think Invulnerability is doable.
As for lockpicks, having lots of money fixes that problem (you can just easily buy them).

If anything then it's money, amount of days passed/left and bullets (you can buy them, but in the Dinner Party mode you can't always easily reach the guy selling them without getting shot).
