Commander Keen in Keen Dreams (also known as Commander Keen: Keen Dreams or simply as Keen Dreams) is a 2D comical-fantasy platformer developed by id Software and published by Softdisk Publishing for DOS PCs as part of the Gamer's Edge disk magazine sometime in 1991.
A spin-off of the Commander Keen series of platformers, Keen Dreams puts players back in the role of the titular child genius as he traverses the dreamland of Tuberia to battle the sentient vegetable king Boobus Tuber and his vegetable army. Unlike other games in the series, he cannot use his trusty ray gun and pogo stick, instead being able to stun enemies by transforming them into harmless flowers using magical "Flower Power" pellets.
The game was one of few that id developed for Softdisk due to contractual obligations from the fact that they, comprised of former Softdisk employees, used Softdisk's resources to develop Commander Keen in Invasion of the Vorticons. It features an earlier version of the game engine used for both Commander Keen in Goodbye, Galaxy and Commander Keen in Aliens Ate My Babysitter and is considered a "lost episode" of the series (or "Episode 3.5").
The game later received a shareware release on September 1992. Although the shareware version contained the game in its entirety, it did not receive the registered version's later 1993 updates and required navigation of an advertisement program before the game ran. A retail version of Keen Dreams was also published in 1993 by GT Software.
