Just a really good game. The things like characters seeing if you’ve killed enemies to decide your ending, the game knowing if you’re doing a ng+, flowey crashing your game during his fight was so new and cool to me in middle school, I didn’t know games could do that back then and it was just so sick, made the game feel alive. clearing the save data in my files so I can do back and get true ending or genocide routes made me feel smart lmao. Great ost too, used to listen to it so much when I listen to tracks on their own I anticipate what would’ve come up when played in full. The story section before asgore’s fight with the music always makes me teary eyed, even after playing it over and over.
