KeyWe made an appearance at The Escapist 's Indie Showcase. In May, KeyWe was one of 55 games featured at the Wholesome Direct. Sold Out showcased the game at their booth at Pax East 2020, along with Disjunction, No Straight Roads, Gestalt: Steam & Cinder, and Radical Rabbit Stew. In February, Sold Out announced KeyWe for PC, with a planned release date of 2021. Rare games such as Banjo-Kazooie and Conker's Bad Fur Day were inspirations for KeyWe's art style. Gessel took inspiration from Terry Pratchett's Going Postal, a story about a conman who is given an opportunity to work as a postmaster. Stonewheat wanted the game to be accessible to families. Grant Gessel is Stonewheat's technical artist, and Joel Davis is the animator. One of the developers drew a picture of a bird wearing a headset, and the team later decided on a game with two birds sending telegrams by typing with their butts. The developers liked the idea of postal birds that couldn't fly, and had to work at desk job instead. During the event, the developers picked a modifier, and was given "Your game must contain a bird protagonist". The game was prototyped during the 2018 Global Game Jam. KeyWe is the first game by US developer Stonewheat & Sons.

More stamps can be received from playing minigames such as playing instruments and riding cassowaries. Players can replay levels to earn more stamps. Beating target times rewards the player with stamps, which can be used to purchase cosmetic items for the kiwis. The main stages task the players with typing messages, placing the correct postcodes and labels on packages, and sorting incoming and outgoing mail. Some buttons may change places, and messages may be written in code. In one level, Kudzu vines have to be removed to move boxes around the office. The puzzles receive modifiers as the player progresses. Each mission has a main objective that has to be completed. The kiwis can also use their butts to collect labels and press buttons. The kiwis can push and pull objects, or grab letters with their beaks.

Players control Jeff and Debra, two flightless birds. KeyWe's story takes place over three seasons: Summer, Wickertide, and Winter. Jeff and Debra have to type the word "pants" by using the keys in the level.
