The boss spawns at the end of Act 2, but it's incomplete:.The final game represents it as a column of red rings in Debug Mode. The auto-roll object (used in Hill Top and Casino Night to force Sonic/Tails into a ball) has also been implemented and is placeable in Debug Mode.The bumper has been implemented, albeit pink, with the inner ring around the star in a palette cycle instead of red and without the inner ring palette-cycling at all.Various other common objects such as the flippers are also loaded into VRAM, but haven't actually been coded yet. While not implemented yet, the moving blocks have their art in the ROM.The triangle bumpers, conveyor belts, elevator tops, and neon tree lights still have their designs from the Simon Wai build.Given the way they're set up, paralax scrolling would've been used a lot here.

The background was given a major overhaul: the buildings are smaller, making them appear further away, and there's an extra layer at the bottom.The Zone reached its final design by the September 14th build. The version of Casino Night here seems to be the same one seen in a few early screenshots.
