That's a really optimized run. You really have movement down. The only thing I feel you could save a few seconds on tho that shop at the beginning. figuring out whether you can afford a single steelskin potion there is not worth 5 seconds. Just immediately skip that shop and wait to buy things when you have a bunch of aura and don't need to use your brain
Yeah, touchscreen makes things way easier in terms of movement (although I've lost some runs trying to lock an egg during a transition and it just hatching).
For the shop thing, I will say that there was only one shop that showed up in the map for the entirety of acts 2 and 3 and I would've had only a little more aura if I went there (admittedly, after spending 750 on the fusion), with the cost being that the extra common items from the forge cause an overflow of items at the bottom which is a minor inconvenience. I agree it's probably better to wait for an act 3 shop in general though.
now that you have destroyed vm speedrunning. I suggest you take a look at the really funny things people have done in endless. Just say anything on discord and I can show you some mind blowing images including but not limited to getting 50000 hp on a single monster, healing billions of HP and dealing billions of damage in one battle, getting 500 rip stacks on an enemy at the same time and stunning voss so much it only attacked once.
I wouldn't say completely destroyed lol, there's still the normal balanced villageless stick effigy less and other stuff that seems like they'd be different speedrunning categories. Yeah I'm in the discord already, saw a bunch of those clips/screenshots the other day (idk how, I think I was scrolling through messages related to the keyword "speedrun" xD). Not sure endless is for me but some of those records are really incredible.
