Interesting idea!
My main difficulty was figuring out what to do first. Once I found the steps, it was pretty easy to do. I had the most hard time trying to find there to put the charcoal xD Maybe you could make the "fireplace" more obvious in some way.
I really like the design of the goblin and the 3D models are pretty good in general.
The music fits the atmosphere perfectly but it got a little bit too repetitive.
The mood is fitting perfectly the creepy theme and it kinda reminded me of Frankenstein concept, which i love! The lightning effect it was a nice touch too!
It was a fun experince overall! Keep it up!
