Anyways, here's all the changes I can remember making:
First of all there's this table to track how many bodies the player has discovered. There's also a little planet which can give a full view of the planet you have recently discovered.
The feet change opacity based on whether the player is walking or not, so that it is more clear that the player has started/stopped walking.
That's pretty much it. There's also some small tweaks but those aren't so important.
