I posted my routing for low% in the first thread, getting only 11 stars and 2 items I think this is the limit for humans, but I also have found a theoretical way to do it with only the bomb defuser.

This would be absurdly difficult, I have barely made any progress even with save states and TAS tools but it may be possible.

I will post updates here in case any crazy people want to try and make this human viable.
