Next steps?

So, I have been wondering if there are any suggestions for any functionality to be added. The game itself, the content was just put together quickly without a lot of thought or detail just as a test of the architecture that I built. The game itself is very simple and short. I focused on building the architecture to handle the following things very easily:

1. Adding new commands. Commands that exist currently are Look, Take, Use, Go, Inventory, Quit, Reset, Examine, and help. 
2. Adding new Rooms, connecting them, and handling interactions with items in each room to include special reactions to doing certain things within the room with the right object.
3. Adding new items, defining specific reactions to certain commands on the object.
4. Building an inventory that you can interact with.

Are there things that people might want to see added to the architecture? The goal is to make something that not only I can use to make creating text adventures, but that possibly other people can use as well. A couple of things I was thinking about adding some of the following functionality. 

1. Save and Load functionality
2. Combat
3. Scoring
4. Exportable game log
5. Hints
6. Converting text input for mobile devices to selectable options.

Any thoughts?
