* (Committing genocide fills you with determination.)

Undertale is a love-it-or-have-it game. There's just no other way to say it. It has: a very flavorful sense of humor, quirky characters, an emotional story, excessive dogs, and a very strange RPG/Rhythm/Bullet Hell mix of a battle system. All of those aspects can be good things or bad things depending entirely on your unique personal tastes. So I can't recommend the game because of them.

What I can recommend the game for is possibly the best decision-oriented designs I've ever seen in a video game. It's a game that lets you to crawl through its story as you please the first time, then begs you to replay as a pacifist for the happiest ending, but then tempts you to play as a genocider to see how far you can go. And if you can go far, you are ensured to have a bad time.

All in all Undertale is one thing boiled down to its essense. DETERMINATION.
