Level (seed/game) creator sugestion

#1
well, i was thinking... how the game would be, if its possible to create seeds/level/game if that was possible, i make a realistic seed/level/game of SCP Containment Breach would be...

Please make level/seed/game creator, so we can create our own seed/level/game, and play it, that would be awsome!

i forgot to say 1 thing, in the seed/level/game creator, we can only add and remove rooms and rotate it, not create the all thing

Wait... WHAT?
