"Curly" was the second level we created and I think we were both still in that "heheh it's fun zooming around the curves" phase.
And the last one...yeah. It really needs two or three levels of tutorializing. There's just no good way to learn the techniques and yeah, it feels like random chance otherwise. And then going forward is so touchy that I still fail it at least half the time even knowing what to do. I thought about making the tail longer to slow it down a little, but we were near the end of the jam and I wasn't sure it would be a simple fix.
So yup. Typical game jam misjudging-the-difficulty stuff. Thanks for playing!
