A lot of ambient things have been added! as shown in the screenshots there is now a night and day cycle.
harder to show in just screenshots is that the trees also gently sway a little.

Now what can't be shown in screenshots is the fact that! There is now sound in the game. It also helps with the feedback when interacting with things within the dungeon; hitting stuff, swinging your sword, getting hit. As in it helps make it more clear that something is happening.
