This looks great! What meshes/models did you use? I am writing a game with a similar aesethetic.

I would probably make the trees etc go translucent when they obscure the view though, otherwise objects above the player's head could cause problems during combat...

It looks good visually, the sense of exploration feels good.

A few points of feedback.
The music doesn't seem to fit.
The buckets of water look like decoration so I probably would not have tried to pick them up.
It also isn't clear that the flames can be put out. To me they look like barriers meant to keep the player from leaving the intended play area.
The pulsing flame spouts have no visual indication where they are. It would be frustrating to be killed by one you didn't know was there.

Impressive work though, it is easy to see the work you have put into it so far. Gamedev is not easy.
