Yup. I Beat the True Arena (Planet Robobot) on my third try or so using Archer, like I did with Triple Deluxe. (Triple Deluxe took WAY longer for me, but that was mostly because I kept losing my Archer on the first part of Soul of Sectonia.) I also dodged the red rings of death on my first try as well. It was a really close call, as I only had ONE HP left by the time I reached the last part of the last fight. But Archer's Camouflage saved me once more!
