Ooh, the new menu stuff is neat, and I like how there's new difficulties, especially there being an unlockable endless mode. Although the jar sizes do counteract the "easy" difficulty a bit, heh. (I'm not sure how well that small size jar would work out should later potions have different symbols that don't combine...)
The aiming feels so much better now, and now it's back to a more expected form of "why the hell did you bounce that way", heh.
The small issues I noticed: Leah's description starts to not load correctly after playing her level and returning to the menu.
The other small issue... well, more of a non-issue, considering the whole "can't lose in endless mode" part where it's the most noticeable, but the orb preview does draw in front of everything, and I actually had some small orbs end up stacked up there where I couldn't see where to aim to merge/knock some out. :P
