Actually the game is quite easy..had to do like 10 extra games to get the last achievement of playing 25 games :)
Game is pretty funny though.
About the 'doves'(swans)-achievement: you should check your updates and reset them. Check out all the updates that improve stray geese to join your flock --> you don't want those 8). After this you'll succeed in 1 game(max 5)
Kinda easy medium badge...dodged 40 without moving(cause I wondered why he wasn't running forward when I pushed right button), 134 when I moved a little left and right
