Become a delivery person on the Cardboard Island. Chat with your friends and neighbors, explore and play minigames, deliver strange boxes and fight through the nightmares where your island is being destroyed by demons. Are you ready to solve the Mystery?
The Mystery of the Cardboard Island
SteamThe Mystery of the Cardboard Island is a cozy game about two genres colliding. By day, you deliver boxes to your neighbors and friends on the island. All is good, calm, but there is something strange going on at the center of it all. By night, your nightmares show the island being burned down by horrible demons: and only you can stop this!
Explore a contained open world while delivering boxes, doing minigames, chatting with the locals and simply walking around! During the day you'll be able to do things at your own pace. Customize your house and your own look, repeat minigames to beat the locals or even the dev ranking!

Deliveries on the island are always a bit special. Chase a legged box around, calculate the best path to deliver pizza boxes before they get cold and more!
You keep having these horrible nightmares. In them, monsters are burning your island. You'll need to go around and rescue your friends, fight and destroy little monsters to eventually find the higher demon and confront them in a cinematic puzzle fight!

Something is going on here. Something no one seems to notice, except you. Why are you having these nightmares? Why do they all show the same night, mere days into the future? During both day and night you'll need to explore, find hidden secrets and chat with the locals to try and discover what is really happening.

All the art in the game is made from (digital) cardboard! We wanted to push this artstyle as far as possible. Houses open up when you enter them, the characters can enter inside one of their own boxes to rest, some animals are made of origami... Come and enjoy this cozy cardboard world.

Want to change how you look? You'll be unlocking all kinds of customization options to change your appearance. You just need to visit the craft aesthetician. But that's not all! As a resident of the Cardboard Island you have a house on it, and you'll be able to furnish it as you'd like!
