Cat Bird is a 2017 mobile puzzle-platformer developed and published by Ryan Carag, under the pseudonym Raiyumi, for Android and iOS. The game revolves around Cat Bird, a cross between a cat and a bird, who is trying to get back to its home planet by travelling through portals at the end of each level. Cat Bird's main gimmick is being able to glide upon jumping, which can be used to overcome obstacles within the levels. The game encourages replayability by counting the player's deaths instead of giving the player lives.
