Session length 42 minutes. Had a few small mistakes and some bad RNG in some parts, sub 35 minutes is definitely possible. However I'm happy with this run for now for being the first one for the White Ending of this game as this run took a lot of planning.

In my run I went for +5092 Sane Mental Health in order to be able to enter the last hallway where you are supposed to meet Her for the last time. Here's the math of my original planning route which may have some small variances like the amount of shots:

Brought joy to a friend with Sleepy Cat x 6 = +300 (Hank, Benzido, Kenny, Chie, The Director & The Man Who Wears A Box) Took the time to speak to Benzido x1 = +50 Took the time to speak to Kenny x1 = +50 Talked to Chie before getting the gun x1 = +150 Visited The Director x3 = +150 Took the green pill x1 = +15
Denied the Man in Blue’s existence = +200 Had a natural healing sleep x1 = +20 Ate some ok food x1 = +10
Read a new issue of Sleepy Cat x5 = +330 Donated Hank some actual medicine = +500 Fed the cat x4 = +400 HAM’N’BEANS x1 = +250 Crafted some great food and took the time to heat it x1 = +100 (hot rice pudding + fruity salad) Ate an ultimate tofuburger with cheese, perfect x1 = +1750 Fed the cat and adopted it x1 = +150 Brought joy to Itchy (the cat) = +50 Talked to Itchy about The Director = +100 Drank a chilled Mexica Cola, sophisticated x1 = +500 Drank a chilled can of soda, lovely x3 = +300 Faced your deepest fears x1 = +1000 (this is for entering the last hallway) Fired a shot = -41 Killed a Thinman x2 = -132
Shot mother in the head x11 = -110

Total = +6092 Sane Mental Health
