Two more Chaos Emeralds GET!
Went through the first Act of the up-in-the-sky level again, stopping off to pick up one Emerald there. Then tried the second Act, but died a few times due to not looking where I was going. Tch.
After that, I went back to the first Act of the first Zone (Leaf Forest, or whatever it’s called) and picked up another Emerald. That means I have five now, with only Zones 2 and 7 left to get one in. Hurrah!
