Indeed, I dropped Tails' emblem location for act one in favor of the GFZ3 - GFZ1 link. I thought it'd be kinda lame to swoosh you back to the start, and since both the cave and the boss arena had water, I linked them together. Worked quite nicely. GFZ1 - GFZ2 on the other hand is a mere paste job, with some minor scenery added (lol bushes)
