Well I had to find some obscure Google doc guide posted in a YouTube videos comment section to figure out how to do the Parker route correctly.
If this is some kind of patreon only perk That's not my problem, it shouldn't have been that difficult to figure out so here's the link for everybody https://docs.google.com/spreadsheets/u/0/d/1opecc1Wkh4iUxIYTlF0c5NtbbmmQ_30fIH2b5JXbqUQ/htmlview#
It shouldn't be that hard to get the best route option for parker. The main love route with the beach cg and bathroom cg with the touch option were locked behind a single interaction with Mark that's easy to miss and not obvious, What a poor story choice.
