Doki Doki Compatibility Quest 3 is a visual novel playable in a browser, created to promote the release of Minecraft Pocket Edition v0.12.1 alpha. Players follow Winsten, a Windows 10 PC, as he attends his first day at Device High, a school for portable technology. There, he can meet and interact with Toshie the iPhone, Andy the Android device, and a Windows Phone named Dossie.
As Winsten meets each other student, he learns that he can enjoy the Minecraft: Pocket Edition experience with them, even though they’re running the mobile version and he’s Windows 10 Edition Beta. Each playthrough takes a few minutes, so you can see him arrange to play Minecraft with all three devices.
