Nice game. Its pretty challenging. When I go to the roof, I cannot see my character, the camera way to high. And when moving I get move backward, until I found out you must avoid the cloud.

Could you tell me what screen size you had? I believe there might be an issue with not all screen sizes being able to see everything.
Additionally, sometimes if you move too fast from the bottom area to the top area an issue like you describe may happen.
I'm glad you were still able to get through it though!
