Commander Keen: Keen Dreams (also known as Commander Keen in Keen Dreams or just Keen Dreams) is a 1991 video game by id Software which was originally released for PCs running MS-DOS by Softdisk Publishing, with all rights owned by Flat Rock Software since 2005. The game is part of the Commander Keen series. In 2013 the game was re-released for Android devices. After the PC version's source code became available due to a crowdfunding campaign, the game was also "greenlit" by the Steam Greenlight community in 2014.
