Not sure what the aim of the game was. I saw the frog popping back up every few spirits, but the dialogue didn't seem to lead anywhere. Visuals and sounds were nice.

Keep catching the birds. Every now and then, the frog will appear by the pond in either the first or second location (I think second after a while) and you'll progress the plot. Oh yes, to get to the second map, go to the cave. To get there, go onto the ledge with the fern at the top of the map. there's a slope on the left you ca go down, though it took me ages to notice.
