Undertale Review (SPOILER ALERT)
A spoiler-filled student review of Toby Fox's Undertale: story, characters, three endings and a short wish list.
Warning, this article contains spoilers.
Undertale is a 2-dimensional role-playing game by Toby Fox.
The story takes place in the year 201x and is about a human child named Frisk who decides to explore Mount Ebott and fall into a place called the underground. The underground is inhabited by monsters who used to live with the humans until a war broke out and the humans were victorious trapping all of the monsters underground by a magical barrier which can be broken by the souls of seven humans. At least one soul from both a monster and a human can have one living creature pass through.
Some of the characters you meet include Toriel, a goat who left her position as queen to protect any human who accidentally falls into the underground, Papyrus, a skeleton willing to capture a human just to join the underground’s royal guards, Alphys, the royal scientist who’s always watching you and always helps you, and so many more characters.
The Art Style is a retro 16-bit environment. The game progress can be decided by your actions and there are 3 endings that I know of which are the true pacifist, where you spare everyone, true genocide, where you kill everyone, or the normal ending where it’s a mix of both.
Overall, the game has made me feel different things from time to time like some of the moments can be funny and some can be a bit frustrating to me. The story is sort of original and interesting to me, and the characters are unique and can make me laugh sometimes.
There are a few things that I would add/change in the game like an actual pause menu, a notification in the battle letting you know when you can spare the monster, and settings.
In conclusion, Undertale is definitely one of the best PC games of 2015 and will possibly be one of the best PC games of 2016. It has that amazing story, entertaining characters, and overall, one of the best games I have ever encountered.
Undertale after 2016
Undertale first came out on September 15, 2015, for Windows and OS X, so this review caught it about seven months in. By early February 2016 it had already passed one million sales. Ports followed: Linux in July 2016, PlayStation 4 and PS Vita in August 2017, Nintendo Switch in September 2018 and Xbox One in March 2021. Toby Fox’s game has sold at least five million copies.
Fox’s next project was Deltarune, a related game set in a different world with familiar faces. Chapter 1 appeared for free on Windows and macOS on October 31, 2018, and Chapter 2 on September 17, 2021. The paid release, adding Chapters 3 and 4, arrived on June 4, 2025, for PC, Switch, PlayStation 4 and PlayStation 5, with a Switch 2 version a day later.
The reviewer’s wish for a proper pause menu and settings never really came to Undertale itself, which kept its small, odd menus on every platform.
