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 can be found under the "Extras" heading from the Main Menu, allowing playback of the cassette tape items collected while exploring Slumberland, set to each domain's parallax background art.
A Nintendo Switch port is 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
I made an in-game music player for Little Nemo that allows you to also take in each domain's hand-drawn, endlessly repeating, parallax background art as you listen to Pete Berkman's (of @Anamanaguchi) amazing soundtrack. pic.twitter.com/pUGEJv982f
