So, Eevee, about your guide. I think that 1-3 1st star coin is actually faster than 1-Tower 3rd star coin. Since the only "time loss" is when you pick up the leaf.

At least I use it, and I saved some time over my pb when I first used it in my run

Greenalink uses 1-T 3rd star coin, idk

Greenalink is not always perfect OpieOP

Oh and I usually dont take the 2nd star coin in 2-GH because sometimes I lose a bit of time there. I pick up 3-1 1st star coin

I don't take any of the star coins in 2-GH, there's a free one in 2-Castle
