Bug! Can't progress because of glitched level

[Kitsune]

Level... 4 I think? has no sound and the level looks like just... solid magenta for the walking surface and white for sky. I can kinda see a weird particle effect for where I need to go, and since I have captions on I can read the story... But when I get to the end and reach what I think should be "land", the world ends and I can just walk off and fall forever.
