Outrun the rising lava up to the highest ledge and shinecharge before touching the crumble blocks. Shinespark across to the door. Crystal Flash, then run back across the crumble blocks and shinecharge before entering the lava. Windup and interrupt using the heat damage. Then run back through the lava to the right door.
