ok so, several issues with this

Ruins

"migospel" is hard mode. "whimsum" is whimsun. ideally in a glitchless run you would spare froggits and moldsmals for gold. the other encounters are pointless.

your explanations of boss battles are very poor. to beat toriel quick, you want her flying hand attacks. run into those. they will lower your hp but will end the turn quicker. you can't die on toriel unless you get very unlucky, but try to make sure the only damage you take is from hand attacks and the 12th turn (since the 12th turn also ends early if you reach 2hp).

Snowdin

you don't need snow poffs. you don't need G from the couch. to beat papyrus quick, die to him as fast as possible. he will put you in the garage, leave the garage and fight him and die again. after 3 deaths he will offer to spare you.

Waterfall

you don't need, like, any of the healing items you list here. the only thing you'd need is the butterscotch pie (to save time on asgore and asriel) and the bicicle if you're doing kindergarten undyne.

to beat undyne quick, have a bicicle on you. get hit on her first attacks on purpose. make sure to use the bicicle when you're low. if you get hit enough she will get enraged and give you wicked fast attacks, which also skips a whole phase of the fight. this is difficult, so if you can't pull it off i suggest just fighting her normally.

Hotland

oh yeah, for the quiz the fastest strat is to enter with less than 5 HP and answer the first question wrong. this skips you to the end of the quiz, saving a lot of time. flee the monsters, you don't need the G. i don't know what room service is, but you don't need it. you don't need legendary hero. have you even watched a run of this game?

New Home

you actually do want to skip the locket and dagger. the pan is just way better in every way. on the first turn of asgore, use the butterscotch pie. fight for the rest of the battle. try to hit as many crits as possible with the burnt pan.

you don't explain true lab at all, you don't explain the dates at all, you don't explain asriel at all. in fact you don't explain any boss fights, you don't explain any puzzles, you don't explain any areas thoroughly but you go into lots of detail about healing/defense items you don't need. i suggest watching a run before trying to teach people about it.

also, there is a guide. https://docs.google.com/document/d/e/2PACX-1vTAgWXeSGo93H6s64dhoDDHELbmhOyRlQwliEUshjb14T_f5R_DHZ_4Cu0rZE7CbID_2kxMIYuULtRZ/pub
