Well designed puzzles and level layout. It was fun to play!
The art was nice! I like the design of the main character, it was very cute and I love the way it was animated. The background art was bit distracting at first. Perhaps if it was a darker shade it would have helped the character and platforms stand out a bit more? I find using less contrast for backgrounds usually work well.
The flight mechanic was fun and I liked exploring the level and figuring out the puzzles.
