About the Game

You're coming back to a dream you haven't had in some time, Nemo. It must feel familiar, but something is wrong…

Little Nemo combines metroidvania exploration with classic 2D platformer gameplay. You'll discover new toys throughout Slumberland, each granting a unique ability that will expand your platforming toolkit, opening up new areas to explore and new strategies for defeating enemies and bosses. Slumberland is full of wildly varied regions, each with its own atmosphere, inhabitants, and surprises, all interconnected into a vast, seamless world packed with secrets and collectibles for the curious dreamer to find.

The waters of Oblivion are consuming Slumberland. It's up to you, Nemo. To save it, you'll need to remember this dream before it's washed away by the dawn and lost forever.

Key Features

  • An original soundtrack composed entirely by Peter Berkman of Anamanaguchi.

  • A world full of hidden secrets, collectibles, and a colorful cast of characters.

  • Challenging bosses that can be defeated by mastering the toys you've collected.

  • A unique Rank Up system for players who love a challenge.

  • Customizable difficulty options for players who prefer to focus on the adventure.

  • Finish in roughly 10 - 15 hours, or spend even more time to fully explore and find everything!

Explore a Nearly Forgotten Dream World

Slumberland is a vast, interconnected world that rewards careful exploration. Your map is your most important tool: it will track your progress and dynamically update based on your current abilities and progress. Use your map to help hunt down hidden secrets or find your way back to anything you might have missed.

Collect Your Old Memories

Toys, PJs, Little Buddies, and much more — Slumberland is packed with collectible items drawn from the corners of your memory, each offering new abilities and upgrades to help you push back the Oblivion. Choose the right PJs and Little Buddy to suit your playstyle.

Slumberland rewards curious dreamers. Beyond the critical upgrades, this dream world is home to many different types of collectibles that you'll need a keen eye and a sense of adventure to discover.

A Variety of Dream Domains

Every area in the game has its own unique identity, surprises, and secrets waiting to be uncovered.

Beautiful Art and Music
The hand-drawn, parallax background and tileset art for each domain pair with their own evocative soundtrack made by Peter Berkman of Anamanaguchi. Make sure to look for a Cassette Tape in each domain to unlock that song in the Music Player!

Familiar Foes
From the simple Burrchin that will bristle at your approach to the Boo-Hoo that will haunt nearby items and chase anyone trying to steal them. Each domain's cast of enemies will keep you on your toes.

Unique Mechanics
Each domain includes its own mechanical flourishes and surprises from the Toy Trains and Bouncing Platforms of Nightlight City to the Toggle Crystals of Crystal Caverns.

Unforgettable Characters
Make sure to seek out the dream denizens living in each domain, as they will all play an important role in rescuing Slumberland. In addition, each domain is home to a Guardian who will be able to help you reach the Palace to find King Morpheus, so that you can stop the Oblivion once and for all.

Play How You Like

Players Seeking a Challenge
With the "Challenging" difficulty option, you'll be expected to take advantage of the game's precision of movement to survive with only 3 hearts. Avoid taking damage and you'll eventually Rank Up, making the enemies of Slumberland even more challenging!

Players Seeking Adventure
The "Fair" difficulty option will disable the Rank Up system and offer you double health, allowing more leniency and room for mistakes. This is a great option for players who want to focus on exploration and adventure with less focus on mastery.

Or Fully Customize Your Adventure
You can even fully adjust and fine-tune your difficulty settings to meet your needs with options like triple health, invulnerability, and time scaling. These options are always available to you in the game's pause menu.
