Nice game! I had a decent amount of fun with it despite the simplicity.
For me though, the music in the background was kinda annoying, so I just muted the webpage...
It fits the theme really well, and I like the bird statues making the rules for the level ( and you twisting them ) in order to find the solution.
The character also plays really well, and the physics feel fine tuned ( to me ).
I like the minimalist artstyle, although I feel the feathers don't really match how the game looks, and the text ( while ok ) feels off/incomplete as well ( maybe some proper GUI could have helped ).
Overall, I really liked it and had a good time.
