Lots of forum questions concern new things in this second version so here's some of the common little frustrations encountered with the new game while avoiding what some may consider major spoilers:

I haven't paid much attention to what they're really called but there's a sack o' something (sugar maybe) that you have to buy in the chicken level, a bottle of cream? culture? to make cheese for cows, plastic trays to process meat for the pigs and hats and cloth for the ostrich levels.
There are 4 different kinds of bears, worth different amounts of money. Beware of the polar bears who can do more damage than previous bears . . .
If you click on buildings, they'll speed up production--but click too much and they'll explode (which might not be a bad thing in some cases . . .)
