Lava Reef Zone

• Even more object layout differences.
• Knuckles doesn't run in at the start of Act 1. He just stands there.
• Knuckles can destroy the four pistons of the driller robot by gliding into them before it begins drilling.
• Shields do not protect you from the debris of the exploding rock badniks.
• The bonus monitors at the end of Act 1 are visible for some reason, and for some stranger reason, the monitors have reversed gravity when released by the goal sign. When Act 2 begins, any monitors that have gone off the top of the screen can be seen underneath the ground.

• The lava at the end of Act 1 does not cool when Act 2 begins, but you can still walk on it.
• Act 2's palette has yet to be changed to indicate a freeze-over.
• The screen does not lock behind your character after having passed the first flamethrower.
• When you encounter Knuckles, his theme does not play, and he laughs after punching the boulder at you. The boulder doesn't make any sounds and won't cancel your Super form.
• The Act 2 boss area does not play the boss theme at the start. It plays it as soon as the boss emerges from the lava.
• The Act 2 boss area does not have a Lightning Shield. The ring pattern is also different.
• The lava in the boss area does not cool after breaking the Prison Egg. Instead, once the results tally has finished, the platform you're standing on will drift to the right a bit, then you'll have to jump across more platforms as the lava can still hurt/kill you. The level music does not resume, either.
• The tunnel at the end of Sonic's Act 2 does not go to Hidden Palace, so you're basically stuck. Knuckles' exit to Hidden Palace works, though.
• Without debug mode, the boss area cannot be accessed directly from the level select.
