For a jam game, a 3gb downloadable is a very big ask. For future jams, I would definitely recommend a lighter final build, especially if you can achieve the same concepts.
That said, this is a charming little game. I liked how the dodos popped out of the egg - I would have liked to see that animation a couple more times, maybe during an end sequence. Having newly planted coconut trees drop coconuts made finishing the bridge a lot quicker - I never found myself hunting for a coconut, so that water from the well was the main factor of time.
I did enjoy it, but the download was a real killer. Good work!
