<tons of spoilers below, proceed with caution>
I've gotten all kinds of pRNG from -44(?) to +15, but I don't think it really matters :P
Trophies:
* salt, water & chlorine
* centipede mandible
* imaginary friend
* neutral ground
* forbidden knowledge
* infinite energy
* a safe word
* a y of X
No idea how to solve Holodeck (it seems like luck = pRNG, but you always enter with positive pRNG?)
No idea how to solve Money (aside from clicking 100k times)
Couldn't figure out how to enter Game Jam and Chaos - I know there are two sets of deterministic rules for dungeon routing, but couldn't figure out when each set is in effect.
