Development
Development of Cooped Up started at the end of 2014, the game's engine and sprites being the first parts of the game to be worked on. Early on in development the game was given the working title "Feeding Time". Multiple times the game underwent major changes. The game was first announced on January 2nd 2015. The earliest version of the game took place on one screen and retained the twanging used in the final game, though the game's overall gameplay was much different than the final version. This earlier version did not work as well as Nitrome expected it to, so the design was overhauled. Despite this, certain elements in this version of the game were carried over into the fully developed version and changed to suit it, some of the game's obstacles and the green bird player character being an example of this.

Due to the drastic gameplay changes the game underwent and the differences between the early and final version, the sprite of the green bird player character had to be redrawn. Nitrome announced in mid March that the game was nearing completion, and later at the end of March that it would be their next released game.

By March 31 2015 the game was planned as Nitrome's next game, and by May 5 2015 the game had been submitted and approved by the Apple App Store, Google Play store, and Amazon App Store. The game was released on May 6 2015, this release date announced the day before on the Nitrome blog along with a trailer. Aaron Steed voiced the narrator in the trailer.
