The gameplay is similar, but I’m posting the last two attempts—out of several I tried just now—that didn't work out.
Here is the first one.

Thank you for the video!
It looks like you got stuck on a rock the first time, and simply didn't make it to the next checkpoint the second time.
This was incredibly helpful—thank you.
For the post-game-jam update, I plan to improve the visibility of the rocks and add difficulty settings.
I apologize for taking up your time, but this was a huge help.
