Nice stage man.
Feedback /ideas
* once you finish the stage crop the sprites (less MB)
* it could be good to separate the sky from the main sprite and give it a smaller delta by adding depth
* change the stage line a bit, the girl looks to big. Maybe "start= 0, 30" Spoiler, click to toggle visibilty
