Prior to working on
Pony Island, Daniel Mullins had just graduated from college and attempted to launch a game,
Catch Monsters through
Kickstarter during November 2014, but failed to raise sufficient funds, and instead found a programming job though still wanted to develop games.
Pony Island was primarily developed during the 48-hour
Ludum Dare game jam in December 2014, in which the theme was "Entire Game On One Screen". The game placed high in both the Ludum Dare's Mood and Humor categories, and was featured in
Zoe Quinn's top 10 games of 2014. Inspired by the positive reception, Mullins prepared the game on his off time from his job for release through
Steam Greenlight, and subsequently published the game in January 2016. Mullins wanted to create a game that defied players' expectations from standard game interfaces, and "flipping them upside down". Mullins had been intrigued with games that are "dark and mysterious", but also wanted to create something that felt like it was not meant to be played. Part of this last goal was accomplished by minimizing the amount of instruction that the game provided, particularly once the player began to reveal the internal code workings, but built these systems on familiar interfaces so that the player would have intuition on what to do. For example, in the pseudo-code sections of the game, he found that adding iconography for locks and keys for the commands the players could manipulate helped them to understand how to interact with the code without direct instruction. At the same time, Mullins wrote the language of the pseudocode to make the programming commands seem ominous as to make the player seem like they were "toying with a system that [one] may not fully understand". Mullins also built in fake
error screens and messages through the
Steam software that appeared to come from the player's friends, to further the unease that he wanted the players to feel while playing the game. Mullins attributed part of the game's success to popular streamer
PewDiePie, who had early on asked Mullins if he could post a
Let's Play of
Pony Island. Mullins believed this helped him to get the game voted on by players for Steam Greenlight. == Reception ==
