After petting a Sentinel, you now regain control of Rani as soon as it starts to dissolve, instead of waiting for the Beer Puddle to fully form.
Fixes in the Park:
You could activate the elevator from outside the Glass Palace. Not anymore.
You could end up behind the bushes on the east side of the bridge. There was no point to it, and now you can't.
Cats are better at finding their way into the Glass Palace. Before, if you had a line of cats behind you, a couple of them would often get stuck for a few seconds before following you in.
Improved lighting in the second section of the Tutorial.
And, of course, a little more work on the Beer Puddle.
