Say what now?
Are you talking about walking into the sky?
If so, that's just because I haven't added the backwall barrier yet.
Try double tapping left and/or right to run.
Try hitting spacebar to jump off of the walls.
Tap spacebar while next to the side of the wall and while shadows are overlapped to jump off the side.
You can jump back and forth between the walls to reach the top of the platforms.
Once you are up top you will be able to walk up the slope that's there. The second slope moves into the background even though it looks the same, so you must move up into the background and right at the same time to successfully maneuver up the 2nd ramp.
It's quite neat if you actually test it instead of just looking at it and saying there's nothing there.
Or are you talking about some glitch that I have not noticed? I didn't test it in MMF2, only in TGF1, so maybe that is the source of the glitch if so.
I'll try it in MMF2 and see what happens.
EDIT: I just tested it in MMF2 Developer and it works perfectly fine. Sorry if I'm sounding rude or something but to me it sounds like you are saying that there is nothing worth looking at here, and I happen to know that there is alot more than meets the eye, because I coded it.
Just ignore the sky and don't walk into it. Nothing is in the sky, just sky. I repeat, no coding is associated with the sky. Think of this as 3d with 2d graphics. It sorta has 3 axis' (x,y,z) instead of only 2 (x,y).
The JUMPing is the 3rd axis. Walking up and down and left and right are the other 2 axis'.
JUMPing is the focal point of the code. That is where you must look to see its value. Jump up to the top of the platform and walk on the slopes there.
