Nice concept, I managed to find all but 3 of the geese. I think I kept coming accross the same 3 ponds, even when following the streams connecting them. Quite amazing how geese manage to migrate anywhere, flying around for hours to pick up their flock only to drop them off 100m from where they started! Jokes aside, I liked it and the game was well done. It was difficult to orient myself because the map was so zoomed in, some way to fly lower and higher to increase your vision would do a lot for this game. The entire flock honking along was a great touch, very satisfying. Overall a great jam entry, keep it up!
PS: a small UX issue is that I personally expected the "geese waiting to be picked up" counter to go down when I picked them up instead of when I dropped them off. The game would probably be easier if I first picked up the entire flock before dropping them off.
