Good to see you got all of your ducks in a row for this jam ;)
Nice little game, reminded me of the old Sega game Flicky (a favourite of mine and I recommend it to everyone)!
Level design wise it would have been nice to start at or near the fountain so I had a better idea of where I was coming/going. And perhaps if the camera clamped to the map borders I would have had a better idea of the map size/where I was in relation to the bounds.
If I would have suggested anything to add to the game it would be for an additional score tier you could get for depositing all ducks at the pond at once. Or maybe that the score was entirely based on how many you bank at once. Either way, I think acknowlegding the chain could be leveraged in some way.
The ugly ducklings turning to swans was a nice touch :D
