This is a lil guide on how to make a playthrough where you get every achievement.
I don't recommend this as the best way of playing, you should do this in a replay.
I used the achievement guide from 'Lil Gibby' as reference.

Welcome to the corner of July Avenue and Yam Street.
Here's a map to guide you:
