I figured it would be a bit obvious that you were supposed to jump over the things because the ceiling was made of death blocks so if you grew you would die.
I completely missed that the reason of respawning was that the ceiling was made of Death Blocks.
But reguardless, Jumping over these things was Exactly what I did.
Reguardless of how I jumped, my jump just doesn’t go far enough.
I have finally beaten that jump!
This jump is Very strict. I could only do it when I was lucky enough.
On my first successful attempt, I failed the rest of the room,
so I had to try another 4 attempts before I had completed the Entire room.
