I never really got this complaint. I mean, you do go through several parts over again, but the latter stages you can skip, and/ or you have power ups to make the first several floors take seconds to get through. I'll agree it was probably not necessary, but I feel it was an attempt to possibly make the temple feel harder as you have to go through several stages to get to the end. I guess I just didn't find it repetitive because I flew past the first few floors after I had completed them.
