Maybe this feedback cannot contribute much to your work, I'm sorry for not knowing anything about coding and that kind of stuff to give helpful comments. I'll just type out my experience as a player.
Graphic arts are much better, compared to your previous work. The difficulty has also increased, which makes me lose my mind as I can't nail this game.
I love how the coins are arranged into the shape of a heart. Super cute, and that type of arrangement makes it harder for players to collect coins. I haven't gotten very far so I don't know if there's anything else. Maybe you could try shaping coins into other things such as arrows and stars. I think it'll be more fun as well as challenging.
I have only made it to the shield, are there some other power-ups ? If possible, I'd love to have a gun so that I can shoot the obstacles (other planes, trees...). As the plane rotates, it's not easy at all to shoot precisely. Maybe you could give points for successfully shooting.
Finally, it's great that you came up with "Rolly Avion". Such a unique name!
Hope you'll keep up the good work.
