A boy wakes from a nightmare that tells him everyone in his village will die in three days, and he has that long to figure out whether the prophecy can be stopped. Deadeus is a 2019 Game Boy homebrew horror adventure made by the solo developer IZMA with GB Studio, and it runs on original hardware as well as emulators. It opens with a content warning, and that warning is earned.
There is no combat. Instead, you walk through the village, talk to its residents, read notes, and choose what to do with each day. The story draws on occult imagery, ritual, and apocalyptic prophecy, and the monochrome sprites make its disturbing moments land harder than you might expect. With eleven endings and no fixed path, finishing once only reveals part of what is going on. Its success helped put GB Studio games in the spotlight, and Incube8 Games later released a physical cartridge edition.
