I've recently been made aware of what the dice do (and that you can just always teleport to the dice room once you have the phone), so that changed the routing a lot this run. Dust collection becomes an issue if I'm trying for the normal door to floor 6 so I opted to get the gun and just do an any% run instead of a pacifist run so I could get the seed on floor 4. Feels nice to get a sub 15 time, even if 6 of these minutes are still just playing the auto-scrolling duster levels.
