The lights on the control towers and hangars in the background are different between versions.

Around halfway through the first section, one of the item boxes contains a full life item in the prototype. It was changed to a 5 shuriken item in the final.

Near the end of the section, the prototype has an extra life in one of the boxes, which was changed to a small life item in the final. The prototype has no fence near the end, whilst the final does.

The background colors are brighter in the prototype, they were made much darker for the final. The start of this section was move up a bit for the final.

There is no item box here in the prototype, but the final added one in. It contains a 5 shuriken item.

This part of the round was changed for the final. I'm not sure why, as the original layout was deadly enough (the item box here contains a bomb, which has a good chance of knocking unwary players out of the open door).

Final

The boss of this round was not completed yet in the prototype, and the supercomputer sprites are around the screen. The laser cannons aren't present either. This was all fixed up for the final.
