I’ll help you make this game super easy!
One of the achievement is to have pixel sex 20 times (I think) which unlock uncle being dense (ignore) dirty room and won’t increase awareness.
I got this achievement on my third day along with the achievement dirtying 10 room to the maximum.
The achievement in this game actually help!
Note: You can save whenever… (outside of cutscenes) rightclick to bring up menu and on 2nd page at the bottom there is save / load / options / quit… And this game is easier to lower your Uncle’s alert level by literally just chatting with him every day.
