After the setup for Tombaugh Boing skip that DillyDogz19 shared with me, I managed to clear over the invisible platforms above Tombaugh's roof and walk towards the transmitter and then right at the drop off and managed to get myself onto the ceiling of the control room in the hostile ASE section, using an open corner to drop into the room, this kept the low moon gravity for the rest of tombaugh and I was able to do what I would like to call "battery skip skip" where I didn't have to get the batter to jump up the stairs and let the monorail fall before the reactor section. More experimenting coming soon.
after getting back (didn't take long it's pretty consistent after playing with it enough) i managed to find a similar route that took me right past that door you need to boing through with the cart. Massive time save
Update
HUGE
don't want to be presumptuous but i think we found the beginnings of our fart skip
Wow that is some massive stuff right there. I started laughing hysterically when you started literally running sideways after respawning. With some more routing I'm sure we could skip even more, potentially even into the broken monorail room. I'll have to test this all when I'm not busy. Fart skip incoming.
I've been testing about getting further but so far to no avail. no holes, no one way collision, no respawning with saves. Not yet anyway. i'll keep going. Huge.
Different route: This route is slower, but I believe it is more consistent and supposedly doesn't require as high of a framerate.
