OMNO is a passion project for developer Jonas Manke. He single-handedly created his Journey-inspired puzzle platformer over the course of five years. While he previously has game experience animating characters for State of Decay 2, his first title has headed in a completely different direction as players set off on a gentle journey of discovery rather than a harrowing journey of survival. Having arrived through a strange portal of light, a mysterious character known as a staff bearer finds himself in a strange fantasy world abandoned by humans during the Great Departure. There is no explanation for why he is there, but there is only one way forward through the swamp. The linear path teaches the basics of jumping, all why trying not to drown. There are very few consequences for making a mistake; every death results in respawning at a checkpoint mere feet away from his demise and he has unlimited lives. The emphasis is exploration without being hampered by fear of failure.
