Developer Over The Moon has announced a new game titled Kill Joy, which is a "systems-driven exploration game" set in a surreal landscape filled with rainbows and unicorns. The game allows players to use foul language as a primary interaction method, inspired by The Outer Wilds, and will be available on PC via Steam, though no release date has been provided. Kill Joy encourages players to explore without guidance, relying on instincts to uncover secrets. Instead of traditional combat, players engage with the world through swearing, eliciting varied emotional responses from creatures. The game features a vibrant dreamscape that hides deeper issues, and players can break illusions tied to entities by making them cry, revealing hidden passages and memories. As players dispel illusions, they collect words, questions, and fragments of meaning to reconstruct their identity through deduction challenges.
