Undertale is an experience.
It's a beautiful game, honestly. It's exactly what it says it is. A game where you don't have to kill anybody. It starts with a child falling into the Underground, and they meet a flower. The flower is a tutorial! There is no fighting, there's only friendship. And friendship is gained by collecting friendliness pellets, so it's good to get them all! You get one, and you take damage. The flower's face warps into something grotesque... but not as grotesque as what could come, as a goat-like person shoos it away, protecting you as her own child. Undertale is... fundamentally an experience for this reason. It's beautiful, in every sense. The pixel art is appealing, the atmosphere is always intense and the characters are memorable, funny, and most of all, complex. Undertale spared no expense when it came to detail - the first time I accidentally killed something, Undertale remembered. This game is a very strong contender for the 2015 Game of the Year, and in the same year as MGS 5, Bloodborne, Splatoon, and Super Mario Maker. It's a game that's full of heart, humor, and most of all, determination.
Undertale: Suceeding with Sparing
Undertale is a rare game that comes along every once in a while and makes a genuine impression on me. While it's not for everyone, it sets out with clear objectives, and, in my opinion, succeeds.
