Thanks! I've one more question: what gift should I give to npcs? Dildos?
Dildos are a solid 20 pretty much across the board.
Rory and Linda like the handcrafted doll a bit more (30) but be sure to save a lot of cotton for other quests (10 for a new outfit for the gal outside the candy shop, 10 for Santa once you hit winter to do that quest).
Dolores at the library has +35 for the dirty book from the porn shop at the alley at the right-side edge of town.
But a dildo is 20 for everyone that takes gifts I think.
Saves time compared to a massage (a hit there is 5, crit is 10)... but if you have any money concerns; just do massages.
Oh, and if you didn't know; save your money and parts and get the 2nd upgrade on the watergun.
It does double your fist damage (one-shot kill with a crit on anything but a the two boss fights).
The sword technically does more damage, but it costs more to make, it has lower durability; and once you're one-shotting, more damage doesn't help.
The gun off the toy store, 12 upgrade kits, and 2 part B drops off the robots in the factory (level 3 of the factory) can get you the watergun. Say 400 in cash plus the drops.
The sword is like 850 + drops, and not significantly better.
