This was done offline with music unlike the chapter 7 IL I just posted, with my mic still on by accident but I only make a few unrelated comments as I needed to help with some things. The music is shown at the side, it's the NieR Piano collections :3

This was probably the more interesting and satisfying of all the ILs I've done as it required a lot more intense routing than others did, mainly at the item collection sequence of the rocks, coconuts and cylinders. I routed the quickest order to collect them in and where they were and aside from a minor mistake followed it exactly which saved a LOT of time as I wasn't too keen on this section casually. Other than that the optimisation is similar to the others with the boost boots used to good effect in the ending sequence. Improvements possible but I have no complaints on sub-5 minutes here.
