Sorry it took me so long to discover that you'd uploaded this!
I really like the style! The visuals and music fit really well together for a fun Voxel Final Fantasy feel.
The environment is fun to explore and you've got the basics of an interesting combat system there.
I'd query a couple of choices (like why is E interact in some places, but enter in others?) and a bit of text in the battles that said what each button did when you moused over it would have been a nice bit of polish.
Overall though, I think it hangs together really well!
