When Crawford revealed the Kickstarter campaign for Frog Fractions 2 in 2014, he vowed to eschew traditional marketing schemes and keep the game a mystery during development.

"Most Kickstarters are very detailed about what you're paying for, but the nature of this one is that you're paying for a surprise," he said at the time.

Since then, Crawford and a crack team of developers have been running at least two different alternate-reality games leading up to the release of Frog Fractions 2. The ARGs themselves are complex and multi-layered, with the creators leaving hints in podcasts and comment sections, within Super Mario Maker levels, and inside of more than 24 other independent games, including Campo Santo's Firewatch. Crawford and his team recently ran through the oral history of these ARGs on Polygon.

The end of the main ARG campaign involved some folks completing an escape room in Portland, finding a key and using it to activate a big red button that read, via a sticky note, "Launch FF2." The intrepid hunters at Game Detectives noticed that the Steam title Glittermitten Grove received a huge update precisely when the button was pressed.

Turns out, that update was Frog Fractions 2. Yes, buried inside a completely separate game about fairies building and managing their forest abodes, published by Adult Swim Games.

There are two ways to access Frog Fractions 2 via Glittermitten Grove, according to Kotaku: Use fireworks to dig in the ground until you find a door that leads to the sequel, or actually play Glittermitten Grove until you find a door in the sky.

Crawford warned everyone about the mind games behind Frog Fractions 2 back in 2014, when he said the sequel would be "larger in scope than Frog Fractions, containing multiple levels of secrets that will take you many play sessions to discover." At least he isn't a liar.
