About Little Nemo and the Nightmare Fiends
A hand-animated Metroidvania Adventure!
Slumberland has been invaded by the evil Nightmare Fiends, and the royal family has summoned Nemo back after a long absence to prevent nightmares from ruling dreams forever!
Take control of 4 characters on your trip through Slumberland! The brave Nemo, the magic-wielding Princess, the mischievous clown Flip, and the agile royal guard Peony - an original character created for this game!
Each character has unique ways to attack and explore. Players can switch between them quickly to create powerful combos and find hidden areas!
Wake Nemo up and explore his house, featuring rooms with hidden items, artifacts to make your characters stronger, and production artwork!
Features gorgeous hand-drawn animations as a tribute to animation and comics pioneer Winsor McCay, including characters and scenes from his work reimagined for modern audiences!
