Self-bought on DLSite. Loved the game after playing the 1.0 which was uploaded here so I decided to buy the complete edition. Hopefully you will love it too.

Gameplay is relatively simple, you buy slaves, breed them to monster, they give birth to new monsters, sell monsters and slaves that can't give birth anymore, rinse and repeat.

Later in the game you unlock new features, such as being able to "uncraft" creatures, automation, creating items, and ultimately, running your own brothel of monsters.
