This is far from being a good game.
The animations are bad, and the interaction between the characters is even worse. There is a slight hint of physical animation/ragdoll that at least is not bugged but the game is just not there
There is basically nothing to do, you place the goblins near the girls and thrust them at max speed to earn 1 coin each orgasm... that's it.
Apparently there is no difference between the three types of goblin, so you can use either of them and the result doesn't change, plus their animations are awful.
You start with 3 girls (OK) to unlock a new one you need 5000 coins which takes a disproportionate amount of time, but you are stuck because you need also the fourth goblin to milk her, another 7500 coins...
There is no feel of progression, no interesting thing to do or to unlock.
Navigating the scene feels weird as you are in ghost mode and possess the goblin to adjust their position.
No penetration, only rubbing, but a lot of clipping...
Overall 2 stars: 1 for the graphics and 1 for the physics that's not bugged (just a bit jittery).
