So, the randomness factors a lot into this. You sometimes need to try a step that's on the walkthrough several times. I've spent some time on trying to decompile the game so I could write something that allowed for more control over the randomness, but gave up.
Yeah from countless retries with the walktrough i only managed to get the walktrough to work with my gameplay once and that was around 90 % of the walktrough being true
All other attempts to follow the written walktrough ended up only around between 40 and 70 % of the walktrough ending up being true
Alot of stuff that changes is the mother in the bathroom situations with the mirror and peeking
And also the catching the mc jacking off in the bathroom and the mom wants a talk often doesnt trigger when u follow the walktrough
It seems that following the written walktrough is more or less a gamble and you have to pray and be lucky that following the walktrough works completlly or close to complete to have a somewhat smooth run
Its been pretty irratating to follow the walktrough and have to redo the game caus certain stuff dont work as its written
And yeah i know some things u can just go in and out a room or location to hope for a better outcome but that can get annoying as well since some times ur doing that for 10 minutes and jack shit happends
And playing the game witout the walktrough is even more of a hassle and confusing
