Undertale’s PC indie success brought its creator fear, guilt … and gratitude

Undertale was one of the biggest surprise hits last year, and this caught its creator off guard.

Toby Fox wrote about the reaction to his indie role-playing game on his blog almost one year after its release (it came out on September 15, 2015). Undertale won over fans and critics with its quirky humor and for giving players the ability to play the game without killing anything. But that success wasn’t all good for Fox.
