Level Design - Among Us Map

Ok, ok, ok. Above all, it's a map purely invented by me and not intended for the game. Most of the assets come from the game itself, some reworked by me to get a desired result.
I love this game and after several hours on it, I wanted to start creating a map as realistic as possible for this game. The problem : I can't try my map. I am therefore unable to check if it is balanced (the height for a level designer) and so ... On paper it works ^^
