I don't think we had too much scrapped. There were a few pieces of polish that we wanted to add to better communicate some concepts to players, the most major one being warning people that the starting/balcony cube needs to be upright before returning to it.
Oh! The other big one is that we had an enemy that was similar to a top with blades, that we made for the Egypt area. We never fully implemented it, despite it being very close to completion.
