Found a method of using out of bounds collision on the spiral staircase to get past the first idol bypassing yorda all together.

In this state, shadows do not spawn because I never triggered the yorda acquisition cutscene.

Currently stuck at the chandelier room with the third idol. Getting onto of the idol doesn't work (Fully modeled collision)

We would have to find a way of getting from floor 2 to floor 1 without dying to be able to get anywhere else

*Yordaless% is a challenge run im trying to do where im attempting to get as far as possible without picking up yorda. Ideally the end goal would be to activate the 2 idol reflectors needed normally to get into act 3.
