The Tixx dungeons so far seem a tad repetitive, but they are fast to complete so it's not a big deal. Wouldn't do repeated runs though.

JP seems fine even for people not that adept at jumping (like me).

In some areas, toy's popping out of the parcels seem to be on steroids and need to be toned down a little.

With most (all?) rewards available through the gem store / TP, this feels less of a lottery than Halloween was, I'm glad Anet did this kind of improvement. Only downside is that you can only obtain two mini's per year without using the gem store.

Haven't tried the bells yet and likely won't

All in all it's a fun update.
