The portal thingy is kinda clever!
There are three blueprints of hi (that's the name of the character in the code): hi, hi VISUAL L[eft], and hi VISUAL R[ight] (just to clarify, I didn't make these names). hi is just normal hi. hi VISUAL L looks exactly like hi, but is translated -10x (the length of a card), 0y every frame (that's why you can't drag it around; key-word: AROUND). hi VISUAL R is the same story but translated 10x, 0y instead. When hi goes through the left (orange) portal, they get teleported to hi VISUAL L. And when hi goes through the other, right (blue) portal, they get teleported to hi VISUAL R. Also to avoid hi falling into the void, the roof/floor extend slightly past the card; and past that are OutOfBoundsBox's that trigger the dead screen when hi touches them.
Woah I didn't know I typed THAT MUCH lol.
Added:
-Loading screen along the dead screen.
-Fixed the bug where; the guy would go out of bounds(Not really a fix but when you go out of bounds, the dead screen would play).
