how to teleport character from one end of map to antoher, witch rendered loop level

Hi. I want to make a pacman game, in witch character would see other side of teleport (something like loop level). Now (as you can see in the link) I can see a wall, but I want the character to see another half of the map. I was thinking on level looping, but i need to render collectables witchout making them actually taking them into physics (win score) account. So i need exact state of assets on another side, so i cant instantiate them from prefabs, becouse if I already collect them, I cant collect them again. I hope I'm cleary enought. Can you give me a hint how to do that, not a full solution, but at least an idea.

Be aware that I'm coding in unity for only 2 weeks, so I'm newbie. Thanks for help. :)
