I think i have an idea get the exact idea in the grand opening cheating ending where every Secret Endings are alternate and they will not count as null secrets you have to do it in the normal way without cheating which makes the game fair and square

i found a problem to get to that ending you need to be lucky and hope you don't get to floor 2 or 3 but i have an idea Make a Strange teleporter item where it only tps you in floor 1 its not that hard to get IT WILL NOT SPAWN ON NORMAL MODE YOU HAVE TO DO BIRTHDAY BASH TO TRY IT its still going to be same as usual you can't go through in floor 2 or 3 this will make it fair for getting NULL ending 2
