Tons of respect for you response time on the feedback. I would have just suggested a difficulty option cause my game doesn't save for some reason and it makes me restart but another way could be adding permanent buffs for completing experiments such as zombie II hunter makes you do more damage to them, dog toy makes them deal less lust damage or snack make you take less damage from bites
The game doesn't save? That's sounds very odd. If the game can't save properly it should probably crash. Can you give me some details?:
Does the saving work, but just reset when closing and starting the game?
Did you lose progress after updating? If so, don't forget to copy your save file over the next time an update comes out.
Are you able to finish challenges? And does this mean the challenges just reset while playing or something?
Difficulty option sounds good. I think the game is too difficult for alot of people too.
