Guardians of Slumberland is inspired by the story of Winsor McCay’s Little Nemo comics and Capcom's NES-era gameplay. Metroidvania-styled exploration plays a significant role as the pajama-clad child protagonist ventures into a vast, non-linear dream world. An arsenal of toys, candy, and stuffed animals allow Nemo to fend off enemies and traverse otherwise inaccessible paths to variously-themed dream zones.
Music is by Peter Berkman of Anamanaguchi, co-composer on Scott Pilgrim vs. the World: The Game, with sound effects by Jonathan Baken. An in-game music player is currently in the works, to be implemented in a forthcoming update, allowing playback of the cassette tape items collected while exploring Slumberland.
The Steam Next Fest demo allows save progress to carry over into the full game. Little Nemo and the Guardians of Slumberland's Nintendo Switch port is currently in development, planned for release later this year.
From the Steam product page:
Little Nemo and the Guardians of Slumberland takes the retro NES-era platformer gameplay of Capcom and Nintendo favorites and brings it to a vast, non-linear world that has been lovingly hand-animated frame-by-frame. You’ll explore as you collect new ability-granting toys and PJs, discover enchanting lands inspired by Winsor McCay’s Little Nemo comics, and encounter a colorful cast of characters — all through the nostalgic lens of an ‘80s/’90s kid.Die Soft Games - Little Nemo and the Guardians of Slumberland
