-SPOILERS- Bucket Loop?

[Storm909]

So i've been playing for about seven hours now, and after a bit..
i've seem to locked myself in 'THE SEQUEL' And the bucket? i mean the bucket is there, yet i have just went though pretty much all of the normal endings (with the bucket) and without, yet i can't find the 'new content' door again or the 'new new content' door

Is this the ending of the game already? or am i missing new endings?
question, do i have to 'DELETE SAVE DATA' in order to go back before the changes? as in before all the balloons around the office or back to Stanley Parable 2 the large area where you see the infinite hole and such

Is there anything else i can do, or more so what to do?

-I have gotten most of the endings, yet now im stuck with the bucket and im not discovering anything new-
-EDIT: I have collected all the Stanley figures and got that ending, just wanting to add that-

There is one thing - Try quitting out of the game altogether and starting it again. After you get to the main menu, quit out of the game again and restart. if you repeat this a few more times, you will unlock the EPILOGUE option on the main menu.

After you've been through the epilogue, you'll be able to go through the 'new content' door again whenever you want. Try taking the bucket through that door for a funny ending, too.

Also try exploring the convention hall again - not much has changed, but you'll be able to actually use the free achievement machine in the basement, and bringing the bucket up to the bucket display room also had a hilarious result.)

Oh thanks! i would have had zero idea to try and do this, but now i've gotten it and going to try it out, thank you very much!
