  1. I love this game. Even though I'm mainly a mother fan, I gotta say, I love undertale too. This game has charm to it. The boss battles are also my fav part of the game. They can be difficult, but if you are truly a skilled undertale player and just an RPG gamer in general, you can get through the bosses eventually.
