Thanks again for all your feedback.
The next step will be a complete redo with a more complete UI that will include some inventory management and all the options that come with it like encumbrance, crafting, etc.
Not sure how to make lore appropriate that a house makes a different sound based on what's in it but I do understand the need you're pointing out. Maybe having different kinds of building like gas stations, farms, houses, factories, warehouses would be more readily identifiable and with a reasonable expectation of different findings for each.
