I finally did it ! After several hours passed throughout some weeks, I really underestimated this game, and most importantly Undyne's fight ! It was really hard. Overall I know there was a lot of mistakes, like the death at Undying Undyne of course, but I'm pretty proud, I'll do more runs on this game, now that I know the route and how to beat Undyne, I'm surely gonna get a better score ^^

Mod note: Time ends on touching the door, so your time was actually 1:16:50 :)
