In June 2013, Fox launched a Kickstarter crowd-funding campaign for the game. More than 50k were pledged of $5,000 goal. Anyone backing $10 or more would receive a digital download of Undertale.

In September 2015, Undertale was released for Microsoft Windows and OS X. The game was partially developed in Andrew Hussie’s basement.

In the game, the player controls a child who falls through a hole in a cave and arrives in an underground world where monsters have been forced to reside after a battle with the human race.

In producing Undertale, Toby got his inspiration from the British comedy show Mr. Bean, the bullet-hell shooter series Touhou Project, and Mario & Luigi role-playing series.

In addition, he got the idea of being trapped in an underground world from the video game Brandish.

Along with being the main developer of Undertale, he is credited for designing the following characters:

  • Froggit;
  • Undyne;
  • Whimsun;
  • Shyren;
  • Moldsmal;
  • Toriel;
  • Loox;
  • Asgore;
  • Knight Knight;
  • Migosp;
  • Madjick;
  • Napstablook;
  • Astigmatism;
  • Whimsalot;
  • Doggo;
  • Final Froggit;
  • Mad Dummy;
  • Moldbygg;
  • Royal Guards;
  • Pyrope;
  • Tsunderplane;
  • Alphys (design).

Undertale sold more than 3.5 million copies. He said:

”Surprisingly, there are many people who like this type of game.”

Toby went on to say:

”Though I did work hard, there’s definitely a lot of luck involved in having a game become this popular.”

The game received many game awards nominations, including:

  • Game of the Year at the SXSW Gaming Awards;
  • Excellence in Narrative at the Independent Games Festival Awards;
  • Best Narrative at the Game Developers Choice Awards.
