Beta 1 will be have ERROR FLOOR is continue after floor 3 end and FLOOR ERROR not have map design yet (in alpha 6 2 floor demo file) I think it's will be using floor 3 because I see floor 3 has 4 power generators in floor layout (that's I found in D62F Demo file) or if you hearing Baldi floor 4 intro Baldi will be saying "welcome to floor 4! Despite what happened last floor you were able to make it" they said that because they pass floor error and say that
also there's 1 Baldi unused sound in game file and they said "Oh noes the power generators is starting run out! You able to fix the tube to make power back into the schoolhouse!" I think It's will be playing when player reaching last exit at floor 3 I think floor ERROR will be play out after end floor 3
I hope you read all
