Neat little submission. Certaintly on theme!

Art style is very cool. Liked the hand-drawn feel of it and the nice touches like the wiggle in the player's bungee rope. Parallax background is very well done too, plenty of variety there.

For improvements, I'd suggest giving the birds an outline. They can be quite hard to see when there is a mountain in the background. A couple of SFX would be a nice addition too. Finally, perhaps adding another mechanic like rings to pass through to earn more points would be cool.

Overall, nice submission. Good job!
