Pony Island is a suspense puzzle game released in 2016 by Daniel Mullins. The game takes place in a demonic arcade game, similar to the urban legend of Polybius.
The Pony Island logo and main menu use Ray Larabie’s Mail Ray Stuff. In promotional material outside the game, there is a glitch effect added to the logo.
The main font used throughout the game is a pixel font which appears to be custom. There is a recreation of this font by CTFonts called “Pony Island”.
Certain characters’ dialogue uses Crumbled Pixels, a Fontstruct creation by dangengneng (a.k.a. Alyssa Diaz). One colorful part of the game uses Yuji Oshimoto’s 04b_30.
