I found the game by chance a few months ago and I liked it a lot!
I was surprised to see that 2 more chapters were added since then. A welcome surprise

Here is a honest review, I really like the game but I don't want to magnify it.
Chapters 1 to 2 are my favorite. I love the relationship between the main character and Gazi. It starts really sweet. Lots of cute scenes as well. I also like the other goblin girls, especially the red haired one. The whole scene in the temple is great and feels natural somehow. The slime girl is an interesting addition in term of character, but I don't really like her design to be honest. At least she can change her appearance...
Chapter 3 felt really short in comparison to the others. I don't feel it added a lot to the plot, or at least it didn't pique my attention. Gazi met with the goblin deity in an important scene, but not much happened besides that, that I remember. The group met some new characters, the girls got new clothes, that's about it.
Chapter 4 was quite good. Only critique I have is that most of the chapter is sex scenes, and there's a lot of girl/girl content. The lesbian scene between Gazi and her friend after the "lesson" felt a bit unnecessary. The scenes are OK, but since the chapter is short they feel kinda heavy. Sex scenes should not take more than 1/3 of the chapters in my opinion...
I hope that the future chapters can reach a better balance between story/intimate scenes. Maybe make some chapters about as long as chapters 1 and 2?
The red haired goblin sounds more adventurous and dominant in that chapter, which I really liked. I'd admit that her scene with the female orc felt like it came out of nowhere...Even with a "crush at first sight", this kind of action should have taken more time I think.
Her second scene with Gazi and Alexi was great in my opinion. I like her showing more of a dominant side. I don't have a problem with her "dominating" Alexi (as other people said) as long as it happens only during her "lessons" with Gazi. And yes, I liked the feet stuff. It was brash and cocky, just like her personality
One last thing: the main character didn't look so much like the main character in that chapter. He felt quite passive. he deserves some character development. The voiceless goblin girl might deserve some more screen time as well.
