Just a few quick things to note to those that don't know. By free-moving over the entirety of Launch Base 2. The final boss area and the Death Egg launch flames are all there, alas no final bosses. Knuckles Angel Island section is explorable to a point. And the weird unused red spheres from the Special Stages are placeable in debug mode on Angel Island. The same red spheres that was discovered in the final ROM. I just realised most of this was probably discovered in the livestream but I missed most of it.
