I'm trying to identify a game I've played as a child, most likely on the NES. The time when I would have played this would likely fall in the 1992 - 1998 range. Sadly, I remember only a small part of it - the part that made it stand out to me at the time.
The main gameplay of the game was probably some RPG or hack and slash type, but between levels (areas? maps?) there was a town one could build. Unlocking space for building would require completing another level.
Unless my memory is mixing games, during the town-building one could fly over the town as a kind of angel figure.
/edit: The time when I would have played this would likely fall in the 1992 - 1998 range.
