@@RedoRegoReho Ha, You should try Genocide Route! The Undyne the Undying Fight is INsane! To access genocide route you must Grind EXP To do that you must kill enemies but, you must keep killing enemies in a area until you get the message "but nobody came..." Then continue to the next era, Rinse and repeat and bam... You've played all routes It can be boring but it's worth it
@@RedoRegoReho all i'm gonna say: you can beat the game without killing anybody and get good end, you can stay on a place grinding for enemies until you enter a fight where nobody came, meaning you get bad ending
