Fun game. However, I would suggest making the banking system more versatile. Would be nice to be able to do more then exchange gems for gold/wood. i.e. exchange gold/wood for gems, exchange wood for gold, and vice versa.
To get the "Bourgeoisie" achievement, reset your upgrades and then repurchase all the upgrades except for Homing Beacon (now you can be more precise), Rabbit's Foot (less gray geese), Rain Dance (no more being bombarded by geese during a storm), and Poseidon's Blessing/Phoenix Pendant (allows you to die quicker to reset).

"Bourgeoisie" was the hardest of the achievements for me.

Got it on the 4th try after that. :)
