It's a shame the old version doesn't work in the browser anymore (or at least it doesn't work for me in Firefox), but it's cool we now have this. Really nice puzzle game. I hope you'll add a selection screen soon though. Starting the game over and over again quickly becomes cumbersome (tried to show the game to a friend of mine on a smartphone, but I accidentally closed the app).
Two questions:
1. Is it intended that you can change the boxes while the bird is walking? I don't think it's a bad idea, adds a new layer to the puzzle solving.
2. What is the flying ability for? I couldn't make the bird flying except on the starting field.
Also, there are two bugs I found:
1. the boxes are clickable even when the chapter screen is visible
2. chapter 1/quest 9 seems broken. When it loads there is no map, and the UI becomes weird
