It's sounds because sounds don't change at all.

Changing it to a text based adventure doesn't change sound at all, but it of course would change everything else.

Depends on what you're considering a "text-based adventure." Most text adventures I've played have no sounds at all. However, some do. Some even have pictures, though most don't have animated pictures of any sort. So the question doesn't really give you enough information.
