Hi, dhward530
Sadly, now there's no official walkthrough.
We have plans to do official walkthrough after we complete making some changes to storypaths for several girls (Jessy, Amy, Maya and some slight changes for Susan) at the beginning of the game. After we complete it, we will make official walkthrough.
For now you can join our Discord server and ask questions about girls paths there - because here we can spoil some story turns for a new players.
Here's link for Discord https://discord.com/invite/6JF9HEN
