Scratch

Yeah, sounds interesting and gave me an idea.
   Thx.

  However, I'll try to explain in words:
You have 2 types of side-scrolling games. #1 Purely 2D (like Mario games) when you move forward or backwards and you can jump; and some other games (#2) allow you to move forward, backwards, up and down AND jump (that looks "like" 3D). In this second type, the game levels  something like lanes or similar and you move through them by moving up or down. If you are in a lower lane and jump, while you're in the air, it could look like you're in a higher on but then you land the jump, back to lane you jumped from.
     If you're in a high lane and jump, could look like you are in the scenario background, but you soon return  to the   high lane you were.
     Tryin to make it simpler:
     NOTE: since Scratch limits me to 480x360 res, I won't make more than 3 lanes in my game. Something like this:
               NORMAL (#1)
        1 <You're here> Jump  A <land here>  [1 ------> A]
                WITH "LANES" OR LAYERS (#2)
       1 <U may be here>  A    <U may land here>
       2 <U may be here>  B    <U may land here>
       3 <U may be here>  C    <U may land here>
         Possibilities:      1 ----JUMP-----> A (same lane) or B or C
                                2 ----JUMP-----> B (same lane) or A or C
                                3 ----JUMP-----> C (same lane) or A or C.

     Anyone got it?

That's simply a GR8 idea, but if I'm not wrong it's not possible coz Scratch only manages x and y axis, and z axis should be something like y but with another name.... I don't know.

Okay, I get it now, you could have the 3 lanes be sprites and have:

<when [space v] key pressed>
perform jump you want

when gf clicked 
forever
if <touching [sprite 2 v]?>// lane #1
set [lane v] to(1)
end
if <touching [sprite 3 v]?>// lane #2
set [lane v] to(2)
end
if <touching [sprite 4 v]?>// lane #3
set [lane v] to(3)
end

You can determine a sprite's projected position on a 2D plane very simply by dividing by the z.  In your case, the closest lane to the bottom of the screen is z=1, then as you go up the screen, z=2, z=3

your x, y, and z are completely independent.  Your sprite's x position and y position are determined by x/z and y/z respectively.  If you want more help, I can point you to few projects that show this or simply make an example.

Please point them. (I love reverse engineering)

If you need help with the actual gravity after this, just ask 

Alright, thank you. But how will Scratch understand "lane=1" means "jump from lane 1 and come back there"?

Would the different lanes be different colors?

I'm thinking in different colors, and then hiding the sprites behind a scenario.

Okay, then this might just work:

when gf clicked
forever 
if <<lane>=(1)>
if <touching color [color of lane #1]?>
change y by(5)
end
if <not<touching color[color of lane #1]?>>
change y by(-5)
end
end
if <<lane>=(2)>
if <touching color [color of lane #2]?>
change y by(5)
end
if <not<touching color[color of lane #2]?>>
change y by(-5)
end
end
if <<lane>=(3)>
if <touching color [color of lane #3]?>
change y by(5)
end
if <not <touching color [color of lane #3]?>>
change y by (-5)
end
end

Sorry I couldn't get the variables to work 
Tell me if this works or not 

Thanks a lot, but I'm not sure if this will work WITH jumping. I mean, you didn't include jumps in your script.
  But anyway it's givin a hint in this hard work.

Well, jumping should work with it, because it's one of my platformer gravity (with jumping) scripts... sorry if it doesn't 

OK, I jump by pressin X. The problem with this script is that I got stuck in one lane, happens the same moving on y axis by jumping or by presing up arrow.
  BTW, what do u mean by "one of my platformer gravity (with jumping) scripts"?

See if this helps:

http://scratch.mit.edu/projects/amcerbu/1006552.

Use the arrow keys to move the ball left/right/up/down, and use the "w" and "s" keys to move it forward and backward. 

If you need me to explain the scripts, I can do that, but I want to make sure this what you're looking for first.

This was one of the projects I was going to point you towards  .  I can't seem to find the others...but I can make an example for you since I'm pretty confident I understand what you want.

Oh wait, found one: http://scratch.mit.edu/projects/Kileymeister/1413602

Checkin' "Help for Daqa".
  First, I think it can help A LOT of people, not just me. Second, I'll have to open and view the project many and many times (in order to adapt it to my game) coz involves a lot of deep thinking to understand, ha-ha-ha!
