Naughty Tail - Dream Corruption

Overview:
Upon the mysterious death of your parents, you inherit a rundown house and farm in the quaint yet deceptive town of Canbe Valley. As you
explore this seemingly prosperous town, you’ll uncover a world rife with corruption and deceit lurking behind every corner.

In Sinful Valley, a realm that pretends to be fair and just, you’ll discover the harsh reality of underground prostitution, brothels, and slavery.
Explore an immersive narrative filled with beautiful girls, each with unique personalities and backstories, and engage in plenty of uncensored lewd scenes​

I noticed the devs of this game are all over Reddit. Excessive advertising of a game kinda tends to turn me away. To those who have played, is it worth checking out?

 

[noonzone]

Well its looking cute enough will try it

 

[itisjj]

Seems like a simple but interesting premise, gonna bookmark this for later.

 

[asdf1234asdf1234]
