Since we do runs on completed files, then could we potentially reroute the arcade? I've messed around a bit and noticed that if you hit the door just right, you can clip up straight to the upstairs machines. This movement is slightly harder due to the weird nature of the upclip, but not getting it shouldn't be a runkiller. It saves a few seconds of movement and if you screw it up you can just do normal route as a backup. Unless upclipping is so slow it ends up losing time (mashing trip speeds up the clipping), there are two definite areas of timesave over the normal route.

Here is the imgur album describing exactly what I mean: https://imgur.com/gallery/XCdEOb0

The Duck Game Wiki provided the picture used for the examples, and let's see what you guys think of this route.

Yes, I thought the same thing (I imagine you're talking about any% / alldevs%). Also, if you don't get it right, you can try again.

My route idea would be to do what you describe: complete the upper section, then the lower section, and if possible, also clip the lower door to get up faster (you might save a bit with that).
