For a start, there's hints on the loading screen, making it easier to understand how to play the game better. The totems and bonuses and now front-and-centre rather than tucked away in the side and the UI has been tweaked to be more friendly.
When playing, you're less likely to run down the five-go limit and the daily scratch card seems a bit more generous (or I'm just being lucky) and appears each time you load (so far). In-game hints appear more frequently, so there's less brain-freeze time and levelling up happens faster. Plus a bunch of extra whizzes and sparkle have been added to liven things up.
