Hmm, that sounds weird because the video I sent was recorded using the version posted on itch (macOS, Linux arm64 and Web versions), so all these seem to allow going over burnt elements.
Would you have more information or a video to guide us for fixing it? Because I never had such bug. Also, what version are you using (Web, macOS, Windows, Linux)? And would you mind at least try using the web version in the browser and tell us if you still have the same issue? Cheers.
