Unfortunately not 😔 I followed both of them to a t and I'm still stuck at that part
Looking back to both guides, perhaps the reason why you keep dying is because you had a "shi*tty opinion"? (← discord, I'm not bullying I swear 😭, they mentioned it's what most players get themselves killed for, most of your opinions matter, don't be a jerk? I always picked options that shows empathy 🤷♀️)
- (this is the only one I noticed that may be the reason why you keep dying in Chapter 5 with gaster) you feel guilty.
Not sure if this will help, but I did notice you mentioning being on Sans route
- sans does not take "no" too well 🥲 (I never said "no" to him before and I doubt I'll ever do so)
- extra: do not let him go, if he leaves? You better pull him back 😃
