The fastest way to build up corruption points in this version is to constantly steal the toilet paper. It works at all hours of the day, if the mom is at work, sister at school, night when everyone is asleep, just steal the toilet paper, it reduces the grind considerably.
This version has an autosave which is slot 1 so save scum slot 2 and keep clicking on the room with the event you want to see, and if you get the wrong event load save 2 as many times as needed...It's better than playing through multiple days and having the RNG screw you out of the event you want for your only evening slot.
The events appear to be on a percentage system i.e. mom's room evening 50% chance she is there so you are forced to click on a room, leave, then click on it again until the RNG rewards you. So for rooms such as dining room or living room with more than one option for evenings save scumming is a must as some events force the time forward against your will.
I've also noticed that events play out in order regardless of current corruption so with 300 corruption you still have to do massage 1 for the mother then 2, then 3, so in that regard there is a build up in the 'relationship' I suppose.
