Much like has already been said, great job on the visuals and polish!
I get pretty far pretty easily — to the point that I'm questioning the difficulty curve. The page description mentions it, but it just wasn't really noticeable after the first area change, which mostly just acts as a head start. That could mean the dragon's faster, the platforms are farther and fewer between, and maybe debris falls more often or with less warning (though I'd be careful with those since they're more frustrating). But I'd just make it become challenging faster.
I think my favorite part other than the presentation was naturally learning how far Gobba could fall before being stunned. I think you could lean into this more and try to design challenging sections where you have to intentionally fall a bit.
A nice touch would be to make the dragon's chomping volume change based on how close it is, or some other indication of how safe you are.
Great job and I love your take on the theme, an extending ladder, very clever! 💙
