I mostly agree.

I can’t tell if Flowey as Kyubey is perfect or poor casting, I think it’s both really.

Poor Toriel, well I guess it’s accurate to what happened during my first play through.

Frisk as Madoka and Undyne as Kyoko is perfect, Sans as Homura is mostly perfect.

Papyrus should have been Sakaya, they both try to be heroes even though they clearly aren't cut out for it, and yet i cant help but sympathize with both of them.

Honestly, I keep putting in my head how Flowey is the bastard child of Kyubey and Psycho Mantis
