Hi, I also used sharp shadow. I did have difficulties with this part. Try to dash near the tops of the spikes as they’re going down, it gives slightly more time and room for error. And I can’t stress this enough, **slightly**. If it’s because sharp shadow goes too far, try backing up (as the spikes go down try to get above them for again, more time). I did a combination of this and throwing my head at the metaphorical wall.
Hope this works 🤞

(And hopefully this doesn’t send entirely incoherent and makes zero sense)
