One more skip i forgot to put in the discord earlier. skips shaman fight, cutscene, and 2 warg fight
Dont hold right at any point for triple switch glitch and it shouldn't crash. The flickering happens sometimes with linux being played on pc. Usually involved screen tearing and random sprites flashing. Can avoid this by not fullscreening and not minimizing the game iirc.
you have to listen to all of the alphys' dialogue before going onto long elevator, you can't skip that in TPE.
if you are using v1.08, then window capture gives a black screen. try game capture instead, that works for me.
it would, the only thing to practice there is undyne the undying and asgore. after you get them down, grinding in the right spots, remembering the kill counts, and learning optimal damage ranges is the only thing left out of that.
Neutral is a good category to start with. I recommend learning PCE and using it to skip the major cutscenes. Also learning the One Cycle Undyne wrong warp. Other wrong warps aren't really important and risk a softlock. Besides that, not dying to asgore.
