If you want a little bit of feedback on the ideas of a future updates here ya go:
0.1 Smithing Update: This is needed as it feels like it is a core gameplay element that is just not there. I would suggest also making an optimization to the items so the game doesn't start lagging with 10+ items on the floor. (Although I have no clue how tough that might be)
0.2 Fighting Update: I'm very tentative about this update. This is because I believe that it is going to be hard to pull off well. If you can keep the lonely ascetic while have other creatures I think that it may just work.
0.3 Exploration Update: I can see the potential here. I think maybe having some kind of cave/s. Maybe stick with that biome idea? It doesn't need to be anything fancy. It can just be some slight coloring variations with some drop rate variations.
0.4 Story Update: Obviously you aren't thinking much about this update currently which I agree with. Although you will want to decide if you want to build some vague lore, have a story line, or both. In my opinion a linear story wouldn't of much to the game as it stands unless you can find some cool way to implement it.
Final Thoughts: Remember to not forget about your core gameplay loop. Also one more suggestion that I have is to the connect these updates together. (Like linking 0.2 to 0.3 & 0.3 to 0.4) Ex. Bat's (0.2) which can be found in deeper caves (0.3) where you'll also find so story. (0.4)
