The art style looked amazing. Especially the main screen animation. The gameplay was a easy though, you can avoid all obstacles by just slowing down, pressing the up button and letting it pass by. Maybe add obstacles that are launched in diagonal directions and maybe some that are moving upwards. Some of the jam games with sky fall gameplay are doing that so you can check them out.
Overall it's a simple and nice game, but needs work on the difficulty. Good job, keep it up!
