Mirage Saloon Changes in Development
Missing Ground
Prototype: If you missed jumping into a gun, there was no ground to save you, and only a boulder with springs. You fall down to the bottom path if you miss it. The boulder moves left and right.
Final Game: A path is put under the spring. There is also no longer a wall blocking the path to the right. The boulder with springs is stationary. The path underneath this floor is the same as in the prototype:
Lower Path
Prototype: One difference about this bottom path below the above section, however, is that there is a spike chain there in the prototype.
Final Game: This is removed, making the section harmless.
Changes to a Gun Section.
Prototype: There is a spike block which moves left and right and a spring block which moves up and down after you are launched up by a gun.
Final Release: Both were removed in the final, I assume this was to make this section much less annoying.
Instead, two blocks are moved further up which serve the same purpose but are much more forgiving.
Team Hooligan
Prototype: There is no curtain for Team Hooligan as it may not have been made yet: I expect that many of you remember this.
Beginning of Knuckles' Level
Prototype: The beginning of Knuckles' Act 2 is different, starting at the outdoor section
