This game is very nice to play. It's easy to understand, the visuals are nice, and the music is relaxing too.
The bird feels a lot bigger than it is shown to be, often being caged and hit by bullets when I felt I shouldn't have. The slight puzzle element to each level makes it also fairly difficult. Adding the 10 second requirement made it very, very difficult.
It could be polished a little. The difficulty felt way too high, but the puzzle element could introduce extra mechanics. Overall nice game!
