So I have recently joined this wiki (a few weeks ago) and I created my first level, Level lotpark. Unfortunately, it got literally no attention, like pretty much every level, and while looking through the level guide, they showed a list that recommended adding to the main cluster 1, which I then did. After finding an empty number, I decided to expand on 10 levels, but there were already six existent levels. So I created four levels and then connected them to the other existing levels, polished, added classes, titles, and a lot of other things. So now there is a collection of 10 levels that are all connected, varying, and even have a new classification. If anybody wants to check it out, https://backrooms.fandom.com/wiki/Level_550?so=search
Remember, they're all connected, so just scroll down to the exits and you'll go in order.
