Today I managed to beat Sans in Undertale. It was satisfying, but not in the way that I liked to kill everyone lol.
To me, the Thief's Hideout was particularly hard, just confusing. There's like so many rooms and it is annoying trying to get pass the guards. It requires much patience.The Thief Hideout was MUCH harder IMO.
This fucking pseudo dungeon is still pissing me off, even after finishing the game many times.
