THIS MAP IS IN FRENCH!!! (but you can still play it if you don't speak this language)

Hello, this map is inspired by Portal, you may notice it with the voice of GLADoS, or even by its name, I spent a total of 7 hours on this project so far, I don't know if I am gonna release the entire map one day, but here is the map with level 1 and 2 done entirely.
I made it so you can understand easily what's going on with the command blocks.

If you want to add stuff to this map by yourself and release it as your own, feel free to make it! I'd love to see someone making something with my stuff, just make sure that you credit me! (1ups_)
If you want to add stuff, I had this idea of "remaking" the Immersive Portals mod in vanilla, but not with simple teleportations, but with the /clone command (in minecraft teleporting a player to another location will always make a weird effect on the player's hand, making it easy to spot, while the /clone command is entirely seamless), once you figure out how to do that, you could also use it in the other levels (spoiler: I used a command converter I found on the web because I am not used to the /execute command in post 1.13 :p)

THIS MAP IS IN 1.16.1 AND WORKS WITH THE MOST RECENT VERSIONS OF THE GAME (1.16.5 at the time I am writing this)
