all of the secret endings for each style are incredibly hard to speedrun. I'm currently trying for demo style and have only gotten the portal once out of a hundred attempts or so. basically, just seeing if anyone has any tips or routes that are consistent.

In the Demo Style's Secret Ending I tried this: When collecting the 7th Notebook, you need to have atleast a BSODA or an Energy Flavored Zesty Bar, then try to come back to beginning place, and try doing the Bonus Questions just like if you just started a new run, same paths, same everything, the only difference is try making the last Bonus Question, the one in the room where Baldi's Basement is.

For the Secret Ending in Classic Style and Party Style, I tried to rely on 1st Prize as much as I could (I alredy did a Party Style Secret Ending run, but in the moment this run isn't verified yet).

good ideas! but i just did normal demo ending for my speedrun
