Hi Peewi, was hoping that you can appoint some additional mods so that runs can be more easily verified. I'd nominate myself for one :)
In Peewi's run he accidentally launches into the town-skullgang beeline with a slug after crossing the waterfall area. I believe you should be able to reliable 'hijack' this beeline by doing the following:
In town, spend the 30 fruit to open the bumper which gets you up to the beeline access point. Go down the pipe to the small pinball area. Grab the slug from this location. Go back up the pipe into town. Use the bumper you unlocked to get up to the beeline access. Launch straight up into the further right beeline.
For any route that travels right out of town toward the divefish this could potentially be used as a reliable way to get there quickly.
