Bah. After the last comment I gave the last achievement one final attempt, and I made it very quickly. Crap. Shouldn't have said anything about it. Hehe. It doesn't change the fact that more badges are needed though.
Additional comment: this game REALLY needs more badges. The first is dead easy, the second is far too annoyingly time-consuming. I still need the Bona-fide Millionaire achievement to complete the game, but it just gets me horribly annoyed, and I have a hard time justifying the time & effort required.
Burgeoise is easy if you do this:
1. Reset all upgrades.
2. Purchase all upgrades that increase the chances of picking up swans, and avoid the ones that increase the geese spawn ratio. Also avoid the Homing Beacon, since it's easier to pinpoint only swans without that upgrade (i.e. it avoids accidentally picking up geese).
3. Only pick up swans (duh). Hurry before the airspace becomes too crowded.
Following the above recipe made me succeed at the first attempt.
This might have been fun, it looked a bit promising, but... well... I guess the "joke" is really to attract as much flame as possible in the comments.
Well, have fun, Sokkenwasser, or is it Sweat-soaked-socks? :)
